PSA: Enable Tor as a simple way to make your node reachable.

Become one of the 10% of node operators that receive incoming connections.
Installing bitcoin core is easy, and with pruning it really isn't the space sink it is characterized as. Even a modest computer can complete the initial block download (IBD) and become a full node. But what some users (90%) find a bit more challenging, is how to become a listening node. Listening nodes are an important part of the network, and are simple enough to enable. I can think of 4 ways to do it:
  1. Operate on an OS and Network that support uPnP, allowing bitcoin to open the ports for you.
  2. Subscribe to a VPN that allows you to open ports through their service.
  3. Manually configure your OS and network to forward port 8333 and 18333.
  4. Run Tor and direct bitcoin to listen through it.
I'll discuss #4. Obviously #1 or #2 are easier, but require a VPN subscription or uPnP enabled HW. And if you live in a dorm or don't control the network, Tor may be the only free option available.
As a bit of background, bitcoin supports three networks that your node can listen on:
Obviously, the more you enable, the better, but here are the basic steps for Tor in broad strokes. If you have any questions post them here and I'll see if we can't help you out:
  1. Download, verify1 and install Gpg4win
  2. Download, verify2, install, and launch Tor Browser
  3. Download, verify3, install, and launch Bitcoin Core
  4. Launch and Admin command console in the directory containing tor.exe
  5. Install the Tor service: tor.exe --service install
  6. CD to service dir: cd %windir%\ServiceProfiles\LocalService\AppData\Roaming\tor
  7. Create and edit a file called torrc with the contents suggested below
  8. Restart tor: tor.exe --service stop && tor.exe --service start
  9. Record the hostname: type .\HiddenService\hostname as
  10. Add the bitcoin.conf options suggested below
  11. Restart the bitcoin-qt program
  12. (Optional) Activate the bitnodes crawler at https://bitnodes.io/nodes/-8333/
It may take a while for your node to show up on bitnodes. I've found the check button sometimes has trouble with onions. Of course you don't need to do it, but it can provide a simple way to check status once your on the list.

torrc file: (replace c:\windows with the proper path as needed)

```

Change to C:\Windows\ServiceProfiles\LocalService\AppData\Roaming

Log notice file \tor\service.log

Bridges may be needed if the Gov't shuts down Tor exit nodes. Get Bridges by

emailing [email protected] from Gmail (only) and uncomment as follows:

Bridge obfs4 : cert= iat-mode=

HiddenServiceDir \tor\HiddenService HiddenServiceVersion 2 HiddenServicePort 8333 127.0.0.1:8333 HiddenServicePort 18333 127.0.0.1:18333 ```

bitcoin.conf file: (entries to be ADDED)

```

Change to what you recorded earlier

onion=127.0.0.1:9050 listen=1 externalip= discover=1 ```

New to BCH, seems to be good and caught up. Why can't Coin Dance reach me?

New to BCH-- most especially since I discovered I had FREE COINs because of the fork!
I have a full node BCH server in my home. It's behind my router, using upnp and has about ~20-25 connections at any one time (mostly incoming, 4-8 outgoing).
I found https://cash.coin.dance/nodes but putting in my public IP says it's not reachable. That web site seems to only count what seems to me to be < 10% of the actual BCH nodes (or am I wrong?).
Have I set up something odd on my end (maybe I should ignore the coin.dance thing and just enjoy my connections.

The White Dragon : A Canadian Dragon Portfolio

Alright guys, Ive been working on this for a while and a post on here by a guy describing his portfolio here was the final kick in the ass for me to put this together. I started writing this to summarize what Im doing for my friends who are beginners, and also for me to make some sense of it for myself
Hopefully parts of it are useful to you, and also ideally you guys can point out errors or have a suggestion or two. I'm posting this here as opposed to investing or canadianinvestor (blech) because they're just gonna tell me to buy an index fund.
This first section is a preamble describing the Canadian tax situation and why Im doing things the way that I am. Feel free to skip it if you dont care about that. Also, there might be mistake regarding what the laws are here so dont take my word for it and verify it for yourself please.
So here in Canada we have two types of registered accounts (theres actually more but whatver). There is the TFSA "Tax Free Savings Account", and RRSP "Registered Retirement Savings Account"
For the sake of simplicity, from the time you turn 18 you are allowed to deposit 5k (it changes year to year based on inflation etc)in each of them. That "room" accumulates retroactively, so if you haventdone anything and are starting today and you are 30 you have around 60k you can put in each of them. The prevailing wisdom is that you should max out the TFSA first and you'll see why in a minute.

TFSA is post tax deposits, with no capital gains or other taxes applied to selling your securities, dividends or anything else. You can withdraw your gains at any time, and the amount that you withdraw is added to the "room" you have for the next year. So lets say I maxed out my TFSA contributions and I take out 20k today, on January of next year I can put back in 20k plus the 5 or whatever they allow for that year. You can see how powerful this is. Theres a few limitations on what is eligable to be held in the TFSA such as bitcoin/bitcoin ETFs, overseas stocks that arent listed on NYSE, TSX, london and a few others. You can Buy to Open and Sell to Close call and put options as well as write Covered Calls.

The RRSP is pre-tax deposits and is a tax deferred scheme. You deposit to lower your income tax burden (and hopefully drop below a bracket) but once you retire you will be taxed on anything you pull out. Withdrawing early has huge penalties and isnt recommended. You are however allowed to borrow against it for a down payment as a first time home buyer. The strategy with these is that a youngperson entering the workforce is likely to be in a fairly low tax bracket and (hopefully) earns more money as they get older and more skilled so the RRSP has more value the greater your pre-taxincome is. You can also do this Self Directed. Its not relevant to this strategy but I included it for the sake of context.
Non registered accounts ( or any other situation, such as selling commercial real estate etc) is subject to a capital gains tax. In so far as I understand it, you add all your gains and losses up at the end of the year. If its a positive number, you cut that number IN HALF and add it to your regular pre-tax income. So if I made 60k from the dayjob and 20k on my margin account that adds up to 70k that I get taxed on. if its a loss, you carry that forward into the next year. Theres no distinction between long term and short term. Also physical PMs are treated differently and I'll fill that part in later once I have the details down.
The reason why all that babble is important is that my broker Questrade, which isnt as good as IB (the only real other option up here as far as Im aware) has one amazing feature that no other broker has: "Margin Power"
If you have a TFSA and a Margin account with them, you can link them together and have your securities in the TFSA collateralise your Margin account. Essentially, when it comes to the Maintenance Excess of the Margin Account QT doesnt care if its in the TFSA *or* the Margin!
You can see how powerful this is.
------------------------------------------------------------------------------------------------------------------------------------------------
So as you can tell by the title, a lot of this is heavily inspired by Chris Cole's paper "The Allegory of the Hawk and the Serpent". You can read it here: https://www.artemiscm.com/welcome#research
Between it, his interviews and my mediocre options skills at the time my mind was blown. Unfortunately I didnt know how to do the Long Volatility part until after the crash in March but I've since then had nothing but time to scour the internet and learn as much as I could.
The way I interpret this isnt necessarily "what you should have right now", but what abstracted model they were able to backtest that gave them the best performance over the 90 years. Also, a lot of my portfolio I already had before I started trying to build this.
As such my allocations dont match the proportions he gave. Not saying my allocations are better, just showing where they are at this time.
I'm going to describe how I do Long Volatility at the end rather than the beginning since the way *I* do it wont make sense until you see the rest of the portflio.

Physical PMs 22%
I'm not sure wether he intended this to be straight up physical gold or include miners and royalty streaming companies so I will just keep this as physical.
I consider Silver to be a non-expiring call option on gold, so that can live here too. I am actually *very* overweight silver and my strategy is to convert a large portion of it to gold (mostly my bars) to gold as the ratio tightens up.
If youre into crypto, you can arguably say that has a place in this section.
If an ETF makes sense for part of your portfolio, I suggest the Sprott ones such as PHYS. Sprott is an honest business and they actually have the metal they say they have. If you have enough, you can redeem your shares from the Royal Canadian Mint. The only downside is that they dont have an options chain, so you cant sell covered calls etc. Simple enough I suppose.
One thing to bear in mind, there is a double edged sword with this class of assets. They're out of the system, theyre nobody's business but your own and theres no counter party. That unfortunately means that you cant lever against it for margin or sell covered calls etc. You can still buy puts though (more on that later)

Commodity Trend (CTA) 10%
https://youtu.be/tac8sWPZW0w
Patrick Ceresna gave a good presentation on what this strategy is. Until I watched this video I just thought it meant "buy commodities". A real CTA does this with futures also so aside from the way he showed, there are two other ETFs that are worth looking at.
COM - This is an explicit trend following ETF that follows a LONG/FLAT strategy instead of LONG/SHORT on a pile of commodity futures. So if they get a "sell" signal for oil or soybeans they sell what they have and go to cash.
COMT- Holds an assortment of different month futures in different commodities, as well as a *lot* of various related shares in producers. Its almost a one stop shop commodities portfolio. Pays a respectable dividend in December
If you want to break the "rules" of CTA, and include equities theres a few others that are also worth looking at
KOL- This is a coal ETF. The problems with it are that a lot of the holdings dont have much to do with coal. One of them is a tractor company. A lot of the companies are Chinese so theres a bit of a red flag.
Obviously Thermal Coal, the kind used for heating and powerplants isnt in vogue and wont be moving forward...but coking coal is used for steel manufacturing and that ain't going anywhere. The dividend is huge, pays out in December. A very very small position might be worth the risk.
Uranium- I'm in URA because thats the only way for me to get exposure to Kazatoprom (#1 producer), which is 20% of the holdings. The other 20% is Cameco (#2 producer)and then its random stuff.
Other than that I have shares in Denison which seems like its a good business with some interesting projects underway. I'm still studying the uranium space so I dont really have much to say about it of any value.
RSX- Russia large caps. If you dont want to pick between the myriad of undervalued, high dividend paying commodity companies that Russia has then just grab this. It only pays in December but it has a liquid options chain so you can do Covered Calls in the meantime if you want.
NTR- Nutrien, canadian company that was formed when two others merged. They are now the worlds largest potash producer. Pretty good dividend. They have some financial difficulties and the stocks been in a downtrend forever. I feel its a good candidate to watch or sell some puts on.
I'm trying to come up with a way to play agriculture since this new phase we're going to be entering is likely to cause huge food shortages.

EURN and NAT- I got in fairly early on the Tanker hype before it was even hype as a way to short oil but I got greedy and lost a lot of my gains. I pared down my position and I'm staying for the dividend.
If you get an oil sell signal, this might be a way to play that still.

Fixed Income/Bonds 10%

Now, I am not a bond expert but unless youre doing some wacky spreads with futures or whatever... I dont see much reason to buy government debt any more. If you are, youre basically betting that they take rates negative. Raoul Pal of Real Vision is pretty firm in his conviction that this will happen. I know better than to argue with him but I dont see risk/reward as being of much value.
HOWEVER, I found two interesting ETFs that seem to bring something to this portfolio
IVOL- This is run by Nancy Davis, and is comprised of TIPS bonds which are nominally inflation protected (doubt its real inflation but whatever) overlayed with some OTC options that are designed to pay off big if the Fed loses control of the long end of the yield curve, which is what might happen during a real inflation situation. Pays out a decent yield monthly
TAIL- This is a simpler portfolio of 10yr treasuries with ladder of puts on the SPX. Pays quarterly.

Equities 58% (shared with options/volatility below)
This is where it gets interesting, obviously most of this is in mining shares but before I get to those I found some interesting stuff that I'm intending to build up as I pare down my miners when the time comes to start doing that.
VIRT- I cant remember where I saw this, but people were talking about this as a volatility play. Its not perfect, but look at the chart compared to SPY. Its a HFT/market making operation, the wackier things get the more pennies they can scalp. A 4% dividend isnt shabby either.
FUND- This is an interesting closed end fund run by Whitney George, one of the principals at Sprott. He took it with him when he joined the company. Ive read his reports and interviews and I really like his approach to value and investing. He's kind of like if Warren Buffett was a gold bug. Theres 120 holdings in there, mostly small caps and very diverse...chicken factories, ball bearings all kinds of boring ass shit that nobody knows exists. Whats crucial is that most of it "needs to exist". Between him, his family and other people at Sprott they control 40% or so of the shares, so they definitely have skin in the game. Generous dividend.
ZIG- This is a "deep value" strategy fund, run by Tobias Carlisle. He has a fairly simple valuation formula called the Acquirer's Multiple that when he backtested it, is supposed to perform very well. He did an interview with Chris Cole on real Vision where he discusses how Value and Deep Value havent done well recently, but over the last 100 years have proven to be very viable strategies. If we feel that theres a new cycle brewing, then this strategy may work again moving forward.

I want to pause and point out something here, Chris Cole, Nassim Taleb and the guys at Mutiny Fund spend a lot of effort explaining that building a portfolio is a lot like putting together a good basketall team. They need to work together, and pick up each others slack
A lot of the ETFs I'm listing here are in many ways portfolios in and of themselves and are *actively managed*. I specifically chose them because they follow a methodology that I respect but I can't do myself because I dont have the skill, temperament or access to.
The next one is a hidden gem and ties into this. I'm not sure how much more upside there is in this one but man was I surprised.
SII- Sprott Inc. I *never* see people listing this stock in their PMs portfolios. A newsletter I'm subscribed to described this stock as the safest way to play junior miners. Their industry presence, intellectual capital and connections means that they get *the best* private placement deals in the best opportunities. I cant compete with a staff like theirs and I'm not going to try. I bought this at 2.50, and I liked the dividend. Since then they did a reverse split to get on the NYSE and like the day after the stock soared.
When it comes to mining ETFS I like GOAU and SILJ the best. None of their major holdings are dead weight companies that are only there because of market cap. I dont want Barrick in my portfolio etc.
SGDJ is a neat version of GDXJ.
Aside from that my individual miners/royalty companies are (no particular order)
MMX
SAND
PAAS
PGM
AUM
AG
MUX
RIO- Rio2 on the tsx, not rio tinto
KTN
KL
Options/Volatility: varies
So this is where we get to the part about options, Volatility and how I do it. I started out in the options space with The Wheel strategy and the Tastytrade approach of selling premium. The spreads and puts I sell, are on shares listed above, in fact some of those I dont hold anymore.
Theres tons of stuff on this in thetagang and options so I wont go into a whole bunch (and you shouldnt be learning the mechanics from me anyway) but theres one thing I want to go over before it gets wild.
If I sell a Cash Secured Put, from a risk management perspective its identical to just buying 100 shares of the underlying security. You are equally "Short Vol" as well, it just that with options
its a little more explicit with the Greeks and everything. But if I use my margin that I was talking about earlier, then I can still collect the premium and the interest doesnt kick in unless Im actually assigned the shares.
But if I sell too many puts on KL or AG, and something happens where the miners get cut down (and lets be real, they all move together) my margin goes down and then I get assigned and kaboom...my account gets blown up
So what I need to do, is balance out the huge Short Vol situation in my portfolio, be net Long Vol and directly hedge my positions. Since the overwhelming majority of my equities are all tied to bullion this is actually a very easy thing to do.

Backspreads
https://youtu.be/pvX5_rkm5x0
https://youtu.be/-jTvWOGVsK8
https://youtu.be/muYjjm934iY

So I set this up so the vast majority of my margin is tied up in these 1-2 or even 1-3 ratio put spreads that *I actually put on for a small credit*, and roll them every once in a while. I run them on SLV, and GDX.
I keep enough room on my margin so I can withstand a 10% drawdown before it sets off the long end of the spreads and then I can ride it out until it turns around and we keep the PM bull market going.
Theres another cool spread I've been using, which is a modified Jade Lizard; if already hold shares, I'll sell a put, sell a covered call, and use some of the premium to buy a longer dated call. Ive been running this on AG mostly.
I have a few more spreads I can show you but Im tired now so it'll have to wait for later.
As I said multiple times, I do intend to trim these miners later but now isnt the time for that IMO. I'm also monitoring this almost full time since I have an injury and have nothing better to do until I heal :p

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

1️⃣GENERAL INFO1️⃣
FREEBITCO.IN can be accessed from any device with internet.
Using a VPN or a TOR is now allowed given that your account achieves certain criteria similar to a captcha free account requirements.
🛑WARNING: FREEBITCO.IN wipes inactive accounts after a certain period! If you lose interest, withdraw your BTC!
📝NOTE: iOS devices (iPad, iPhone) are restrictive. The only way to access is via website, as BitBot isn't available.📝
FREEBITCO.IN is what's called a "faucet", a site that gives a small steady stream of crypto which FREEBITCO.IN does through hourly rolls and interest accrual.
FREEBITCO.IN also hosts other means to win or earn crypto, you can gamble with Multiplier, or bet on world evens and crypto prices.
After your account reaches 30k Satoshi, you begin to collect interest. The site also offers lifetime referral commissions, explained later in this guide.
All you need to start is an email. You can add more verification options for security later on. I would highly suggest it. Use a junk email though.
2FA and MFA are strongly suggested. A password should be 15 characters long. I suggest Google Authenticator for your 2FA needs.
I know you can definitely access this site from Brave Browser with add blockers enabled. I'm sure it will work with others. Even without an ad blockers, they only advertise their site gambling and games, no 3rd party adds that I've seen. It's not too invasive or spammy either.

2️⃣POST INTENTIONS2️⃣
This post is both an advertising platform I use, and a guide I've made to help those interested to automate and optimize earnings.
For those of a cautious mindset, I've uploaded all of FREEBITCO.IN's information on interest accrual, security, and proof of mining on Imgur, in case you're worried about visiting the site.

3️⃣MY EARNINGS3️⃣
So at this point, with hourly claims and daily interest, I'm bringing in roughly 8978 Satoshi (or .70$ USD with BTC at 7804$ USD) daily at full optimization on one account, and two other self referred accounts without lifting a finger. This is before the fact that a hourly roll (claim) can reward up to a max of 200$ USD worth of BTC (percentages in section 5️⃣).
They also have a weekly lotto (tickets awarded with every roll and referral roll) with the last 1st place winner receiving .32769156 BTC (2587$ USD at current bitcoin price).
This is also not including my current commissions on accounts not owned by me. In this post I will describe some of my strategies I've incorporated, and some insight into how this website works.
To offload or withdraw bitcoin, you're going to need what is called a "wallet". I personally use Coinbase (available on mobile or desktop) as you can sell it through here as well and easily move money to Paypal or a bank.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
4️⃣HOW DO COMMISSION REWARDS WORK?4️⃣
If you are already on FREEBITCO.IN, do you have someone who referred you? Do they share commissions? If not, why not make a new account and join me, where you'll get a return on everything you earn.
As you can see, large affiliate groups don't share anything, hoarding hundreds of thousands worth of BTC earned off their referrals
I share 50% of my commissions. I get 50% of your roll rewards, 25% of your interest, and 0.4% of your wagers. All of this is paid out by FREEBITCO.IN as a commission, so it's not pulled from your rewards or held BTC.
So the more you're active, the more you'll receive from me weekly (being active is doing anything that I get commissions from). IMPORTANT: Your (and all referrals) shares are based on activity, so if you are inactive for the week, you get a lower % for that week. If you're the most active of my referrals you get a higher percentage of what I share. This is to incentivize being active and to stop people from getting a cut without doing anything.
If you have FREEBITCO.IN automated, you don't have to worry about this. However, having a larger bankroll to earn interest, or playing Multiply BTC (I do not suggest playing unless doing so to meet auto roll requirements) will increase can your activity further.
Commission Structure
Here is some proof, I've actually shared about 2/3 of all commissions
Commissions update 12 January 2020
Here is a proof of Payment section per individual
📝NOTE: I've noticed when I was creating the images of commission sharing that the "RECENT" blocks are showing zero. If you look at totals from the first image, you can tell I'm actively sharing with all of my referrals.📝

5️⃣SOME CLAIM STATS5️⃣
You can earn AT LEAST .00000552 BTC (.048$) daily when automated (or claiming every hour on the hour) before bonuses (like using reward points to increase rewards 1000%). After some testing, it seems that this amount will always be about .048$ worth of BTC, base claim rewards no bonus active.
After .00030000 BTC, you accrue compounding interest at a rate of 4.08% APR, paid daily. As soon as your daily interest is accredited, it too starts earning interest. The daily interest rate comes out to ~0.011% of your total held BTC.
FREEBITCO.IN gives you a roll once every hour, free
📝NOTE: Roll rewards fluctuate inversely with BTC price. BTC goes down, roll rewards go up, vice versa. The BTC rewards USD value will be extremely close to the values represented below.📝

6️⃣MULTIPLY BTC STRATS AND INFO6️⃣
🛑!WARNING!, NO STRATEGY IS 100%, THE MULTIPLIER GAME IS GAMBLING, YOU CAN STILL LOSE YOUR WHOLE BALANCE IF YOU PUSH YOUR LUCK.🛑
UPDATE: I decided to do some research after some odd outcomes when extensively testing some of my Multiplier strats. Turns out FREEBITCO.IN does indeed have a house advantage that isn't too transparent. Longer sessions are almost always going to come out negative. If you still plan on playing, do short sessions, once daily max, with lower amounts.
There are a couple methods to play the Multiplier with a reduced risk (but still a risk) here as well. I would suggest small play sessions.
STRAT #1
My preferred settings for AUTOROLL on MULTIPLY that I've had the best success rate with to date. (preferably with .00005000 in ACCT for best results)
BET: Minimum
ODDS: 3
ROLLS: (doesn't matter, 100)
BET ON: alternate
STOP BETTING PROFIT: .00000050, important as the bets will get exponentially higher with every loss. Win in small increments.
STOP BETTING LOSS: Set a loss limit if you want, I have mine set to .00001 and haven't reached it
ON WIN: select increase bet 0%
ON LOSS: select increase bet 65%
RANDOMIZE CLIENT SEED: yes
DO NOT REFRESH: yes
Here is a pic of the settings
Anything else doesn't matter. Make sure the boxes are checked for the above options.
With this strat, I've won positive on one account, about .000077 BTC, and I've only played 5 or 6 times, at less than 2-3 minutes of play time a session.
STRAT #2
Good for accounts with a low balance. I've had a surprising amount of luck with this method, enough so that I thought I'd post it here with an update. This could work well for accounts with less than 1k Satoshi, as a losing streak wouldn't be a huge loss. For this strat, you should have at least 189 Satoshi in your account.
BET: Minimum amount
ODDS/WIN CHANCE: 189 or %0.5
ROLLS: 189 (remains the same no matter if you bet more)
BET ON: High or Low, but not Alternate.
STOP BETTING ON PROFIT: Minimum amount, once again, you want continuous small wins
UPDATE: Conducting more tests for viability
I played these settings 10 times, I came out positive 8/10 times. In the end I was positive 433 Satoshi total with selecting "hi".
On selecting "low" I went positive 5/10 losing 525 Satoshi.
On selecting "hi" and betting 10 Satoshi, I went positive 3/10 times losing 9708 Satoshi.
On selecting "high" and betting 100 Satoshi, I never went positive, 0/10. Losing 189000 Satoshi (~15$ USD).
There does seem to be a pattern of losing more when betting more. Like anything gambling, there's probably a house advantage that's not too transparent.
Win small lose small.
Pic of these settings
STRAT #3
Another strategy I've tried is betting most of my balance once occasionally with a 94.06% chance of winning. This is, eh, alright to risk OCCASIONALLY, but a loss would set you back more than you ever made using this strategy, which happened to me, I lost about 40 USD worth of BTC after making maybe 5 USD.
THIS METHOD IS GREAT FOR MEETING NON-CAPTCHA ACCOUNT REQUIREMENTS!
Playing this in auto roll, out of 20 rolls I'd always lose at least once, putting me into the negative. Even with 10 rolls, I'd more often then not lose at least once.
Pic of these settings
There are other strats out there, such as the "Martingale", which is essentially doubling the bet amount every loss, then resetting your bet to minimum after a win to in theory "win back what you lost". At 47.5% odds of winning, I've had loss streaks that would drain my account.
My summary for Multiply, use sparingly. Don't use it as your primary means of earning. Use once or twice daily, limit play sessions to 5 minutes max.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
7️⃣AUTOMATION7️⃣
📝NOTE: FREEBITCO.IN captcha requirements seem to be tiered, with requirements for Captcha free upscaling when you BTC holding passes a certain threshold.
I'm currently testing, as is another team member (Shout out to u/SrExtreme69) , what exactly these thresholds, if holding at these thresholds increases the length of Captcha free rolls, and at what amount does FREEBITCO.IN no longer require these to be met.📝
📝NOTE: To start automating, remember to verify email and setup 2FA or the Captcha will still appear even if your account meets Captcha free requirements. Check the site occasionally as Captcha free roll requirements can change. After certain held BTC amount you don't need to renew your requirements. I haven't had to achieve new requirements in over a month.📝
📝NOTE: You may need to manually roll for a bit until the the ability to achieve a Captcha free account becomes available. It doesn't show at first.📝
📝NOTE: It's very difficult, if not impossible to automate on iOS devices.
First of all, getting to this point can be a grind, but once achieved you'll have a steady flow of BTC with options to increase earnings through rewards claims using RP. I would suggest going to your PROFILE tab on FREEBITCO.IN and disabling lottery to increase RP production when starting out. Using other apps or resources to supplement income is a good idea as well.
On the FREE BTC page, there is a blue text hyperlink with requirements that need to be met to make your account captcha free, thus allowing you to enable autoroll on extensions or apps. It has multiple ways to achieve this and they can change, so if your autoroll has stopped, check to see if these requirements have changed.
Here are the requirements. (Amounts vary)
It seems only two of these requirements need to be met.
The less risky and easiest method is to buy lottery tickets and bet with jackpots on. Even better is depositing bitcoin if you have that amount.
The POSSIBLY least expensive method is to bet both regularly and with Jackpots enabled on MULTIPLY (for higher amounts required, IMO Multiplier strat #3 works best)
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
8️⃣OPTIMIZATION AND USE OF FREEBITCO.IN8️⃣
For computers
I would suggest using Firefox, as you can add functions and tools to your bar up top. One of the being a "auto roll" for FREEBITCO.IN, still requires a "captcha free" account. Turn it on and let go, check it occasionally to make sure its still going.
Autoroll firefox add-on link
My link again for ease of access
Not my preferred method, but good for a second account, as using a computer means devoting more attention to FREEBITCO.IN in an inconvenient manner if you are just starting out. After Captcha has been removed, this becomes more hands free, but not as profitable as using bitbot, as you can't autoclaim RP rewards.
I haven't tried many methods besides using Firefox addons, as I'm wary of sources or intent when it comes to 3rd party scripts or programs. If I find any trustworthy scripts or programs, I will update here.
For Mobile
🛑BITBOT WARNING, IF YOU USE BITBOT TO ACCESS FREEBITCO.IN BEFORE USING MY REFERRAL, YOU WILL BE REFERRED THROUGH BITBOT, AND THEY DON'T SHARE COMMISSIONS AS FAR AS I CAN TELL🛑 My Link again
📝NOTE: iOS devices (iPhone, iPad) do not have access to BitBot, nor do they allow extensions/add-ons on their browsers. I have not personally found a way around this. You may still access the site and manually roll.📝
I use BitBot. This is the best place to start from IMO. You can set it to notify you of rolls and gives direct access to the site from the app (you can also access the site from any device with internet). Once your account is "captcha free" you can set it to auto roll AND automatically claim rewards every 24 hours (RP increase, BTC increase, Lottery ticket Increase).
📝NOTE: Bitbot allows auto roll from the app for accounts over 500 RP. This isn't permanent, as it uses your RP. You'll need to log onto the website through a browser to achieve captch free account requirements, which Bitbot does recognize, which allow completely free rolls.📝
📝NOTE: Accessing FREEBITCO.IN through BitBot doesn't allow access to the Hi-Lo or betting games.📝
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
9️⃣STRATS TO INCREASE EARNINGS9️⃣
Bitbot optimization
I started manual claims by setting roll notifications to "ON" for a while until I supplemented my BTC in FREEBITCO.IN with what I was collecting from my miner and CryptoTab. Once I was able to AUTOMATE and I had enough RP to claim the RP BONUS, I set it to do that automatically every 24 hours as this nets more RP than you spend (EG, 100 RP roll bonus costs 1200 RP, but can net 2400 RP if claimed every hour). Eventually you accrue enough RP to claim the %1000 BTC bonus, probably at a rate of once or twice a week.
My current BitBot settings now that its auto claiming, I have the 24 hour auto bonus claiming 100 RP roll bonus and 100% claim bonus, spending a total of 1520 RP, but I'm making 2400 RP with the RP bonus, leaving me 780 RP in the positive each day. Every now and then I'll stop the auto bonus claim so I can buy the 1000% claim bonus (3200 RP). So on a normal day I'll make about 1344 Satoshi. Bitbot auto bonus settings
Once your accrue more referrals, or save enough RP, it's possible to claim the 1000% BTC roll bonus multiple days in a row. This is just about as optimal as you can get for auto rolling.
Self Referrals
If you have two devices (phone and computer preferably) you can make two accounts as long as one uses a different wifi or internet connection, as the roll rewards tracks IP addresses for roll counts. So if you have 2 devices on the same network, it sudo links accounts, so if you roll on one, it restarts the timer on the other. This allows you to collect referral rewards from yourself. Effectively adding 25% of interest and 50% roll rewards.
I currently have a phone autorolling on BitBot with a computer autorolling on Firefox with a tool to roll automatically as long as the page remains open. My computer account is referred from my mobile account, and is currently bringing in an extra .000015+ BTC weekly (currently, total will be this Sunday and I will update).
I've also made another account on my partners phone, linked it with bitbot and got it auto-rolling. Once bitbot is going, its non-invasive and you can silence notifications, it also uses minimal data.
Supplementing with CryptoTab
I'll use CryptoTab on my computer 24/7 to earn BTC from that while I have FREEBITCO.IN running. I also have it running on my phone at night when I sleep and on an iPad I have that I don't use much, its server mining, so no worries about battery on mobile devices. On computers it does actually use your processing power. You can directly deposit into you FREEBITCO.IN accounts.
CryptoTab Link
I've used it for two weeks and have earned a total of .000454 BTC (3.60$ USD). Not huge, but enough to start collecting interest on FREEBITCO.IN and to get the capthca free account requirements.
Supplementing with Cointiply
🛑WARNING: Cointiply's main currency is the constant, weighted against the dollar (10,000 coin/1USD). This means your actually BTC holdings will fluctuate with BTC's price.
For this reason, it's my strong opinion that DON'T HODL in Cointiply as you're not holding actual BTC.🛑
Cointiply is a great site to earn decent amounts of COIN which translate to SAT's. Earn coin, withdraw to FREEBITCO.IN (as you actually hold BTC in cointiply).
I also use an ASIC miner (Antminer s9i, DIY liquid cooled and overclocked with BixBit firmware), and whatever I earn I'll put that into FREEBITCO.IN to collect interest. If you want, I may be willing to do a rental.
⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹⏹
1️⃣0️⃣ADVERTISING YOUR LINK1️⃣0️⃣
📝NOTE: Since this faucet has been around a while, many people privy to sites such as this are already signed up. So getting referrals can be a slog. My tips for your ads is be genuine and don't hard sell or post "too good to be true" sensational ads.📝
COINTIPLY
This is another faucet. Its structure is a bit different from FREEBITCO.IN, as you complete offers to earn coin. Within this site (also an app) users can earn coins by doing PTC ads (and other offers), this is a good method to get exposure as you can advertise as well. Using this method my traffic for last week as about 800 people.
13000 coins buys about 1000 "clicks" on your ads. They also have options to advertise to people based on location (these options will increase or decrease cost). After your first ad, you usually get a 10% off coupon good for 7 days as well.
You can earn this amount within a day doing surveys on Theorem. I've done surveys before, and this has to be one of the best surveys sights I've ever done. Very rarely do I get kicked out mid survey, and if I do, I still get partial pay.
I will also use "Hideout" on my computer and leave it running. It has to be the open tab on your browser, with the browser open, not minimized. Let it go and check it occasionally as it has a timeout at roughly 2-3 hrs idle. As of now this is the best passive method of earning on Cointiply.
PI NETWORK
Pi Network, an ICO (Initial coin offering) based on trust and social media is another good medium for advertising. I will usually see 15-20 people click on my link with 2-4 ads posted per day.
Just go to "chat", select "random" and post an ad in the chat channel. No charge.
My tip, keep your ads short to medium in length, don't spam.
XYO NETWORK/COIN APP
This is another crypto earned through "geo-mining". On the "coin" app you can do a "geodrop" where you can leave a note. Just click on the box with a parachute icon, select "any" on the "Tile" selection. Leave your ad in the "note" section.
It costs 10 "COIN" at the very least to do a "geodrop". This method may not be worth it if you aren't already involved in the program. To earn a substantial amount of coin, you'll need a subscription or a "sentinel". Sentinels can actually be purchased for under 20$ nowadays (depending on site) and is the best option to earn. Without these you'll only make approx .05-.18 coin every 30 seconds if you're actively moving.
My tips if you plan on advertising on this platform, once again keep it short, and only advertise around 7-9am and 4-6pm, as this will be peak mining hours with people driving to and from work.

Help setting up Bitcoin Core node with Tor hidden service

I am trying to run a full node with Bitcoin Core and get it running as a Tor hidden service but the steps I am following are from many sources and I feel like I have been missing steps in between, not to mention that my technical skills are fairly basic.
Here's where I'm at (Windows):
Can someone please tell me if I've missed something or if I've done it right then how to check that I have?
Thanks!
Update: Currently I have a "work-around" by running tails in a VM and running bitcoin-qt inside that. Because it's a livecd if it gets shutdown for any reason I'd have to set it up each time so I would still like to get the full node running with Tor on Windows.
I am using bitcoin-qt.exe from the Windows installation of Bitcoin Core and using any combination of the network settings to get it to use Tor and it does connect to onion addresses, sometimes one or two and the remaining of the eight are normal nodes.
I can't figure out how to make Bitcoin Core only connect Tor nodes instead of none or a mixture.
Update 2: Instead of using the Tails in a VM workaround, I have the windows Bitcoin Core Node running properly over Tor now. I still have to wait a few days at least to see if I can get more than two incoming connections.
I read in many places that port 8333 had to be opened in order to receive incoming connections but I have been assured that doesn't apply to onion nodes and that checking getnetworkinfo with bitcoin-qt console shows onion as reachable is proof.
There was also an issue with Tor not working with the CookieAuth when that set was added to torrc. Simply CookieAuthFile needed to be added.
I'm adding these notes in case any other windows user has trouble getting their node running with Tor.
SYD4uo was a huge help and I appreciate those others that took the time to give advice. Cheers!
This was also very helpful

Running a full node over private VPN. Is there a guide?

Hi,
I've setup an OpenVPN server on a VPS. I am running a full node on my personal computer with only outbound connections and without inbound / incoming connections, because my ISP doesn't let me port forward any ports.
I've connected to my VPN as a client, and have enabled port forwarding on it by doing so:
/etc/sysctl.conf: net.ipv4.ip_forward = 1 
Despite this, I'm unable to still have incoming connections over port 8333 even after being connected over the VPN. Are there any other iptable settings to be done for Post routing and pre routing? Is there any available guide for this?
Kindly help me out with this if anyone has setup one already.
Note: I'm running an OpenVPN access droplet on DigitalOcean over Ubuntu. Also on my personal computer, my firewall is already configured to allow inbound and outbound traffic via port 8333 (tcp/udp) through bitcoin-qt.exe.

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running.

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running.
Official node scanner list: https://scanner.vertcoin.org/nodes
Since every full VTC node can only serve so many clients, it's important to do your part for the Vertcoin network and run your own full node.
Q: WHAT IS A FULL NODE? A: Full nodes maintain a copy of the blockchain/ledger, distribute it to those downloading it, confirm transactions, and further spread out all of the previous functions to make the network more resilient. https://bitcoin.org/en/full-node
Q: Do I need to be a miner? A: No, you don't need to be a miner. Miners create new blocks. Full nodes simply share existing blocks (the entire VTC blockchain) with the rest of VTC wallet users.
Q: How do I run a Full VTC node on Intel NUC? A: Intel NUC Vertcoin full node installation done using Windows guide: https://github.com/vertcoin-project/VertDocs/blob/mastedocs/FullNodes/intel-nuc.md
Q: How do I run a Full VTC node? A: It's actually quite easy to do. If you run Vertcoin-QT (Vertcoin Core Wallet) on your PC/MAC desktop, keep it active in the systray. Then, make sure that you map the public port 5889 of your router to the port 5889 on the machine running Vertcoin-QT or vertcoind. For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background.
Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background.
Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

Understanding BIP149, redeployment of Segwit with BIP8

I recently published BIP149 and would like to take a few moments to explain the details of this proposal.
BIP149 is a completely new deployment of segwit, which I propose if the current BIP9/BIP141/143/147 segwit deployment fails to lockin/activate by November 15th.
BIP149 cannot be run on mainnet now, and there is code in the reference implementation to prevent it from running. It is incompatible with the current segwit deployment on purpose to remove unnecessary complications.
Essentially, the idea is, if the current segwit deployment fails to activate by Nov 15th, we can release new software that has BIP149. This uses BIP8 to activate segwit by July 2018. Miners will still be able to trigger activation by 95% threshold signalling as normal. In the 8 months from November to July 2018, nodes will be able to upgrade to BIP149. If segwit is not MASF activated by July 2018, there will be enough of the economy running BIP149 that nodes can begin enforcement. What will actually happen is on the first retarget after July 4th, the BIP8 state machine will switch to LOCKED_IN status for two weeks, and then on the following retarget, ACTIVATION will occur. The rationale here is in 5 months we achieved 70% saturation of witness capable nodes, so by the time segwit timesout with all the urgency and demand people feel for segwit, we can expect them to upgrade at least as fast, if not much faster. I have spoken with a number of developers who think this is a reasonable assumption.
Background, I had hoped to be able to release a BIP that can be deployed concurrently now with segwit, but, there are various technical complications in implementing it cleanly and making it easily reviewable. I had various feedback from others in previous iterations and in order to get the widest support from developers especially concerned with predictable results and thus safety, I came to the conclusion that the BIP will get the widest support by not attempting any shortcuts and by removing all complexity. I know many people want segwit now, but, I think we should just bite the bullet and do it the BIP149 way. I already made a shortcut BIP with BIP148. I will discuss the pros and cons at the end.
Back to BIP149, this is a completely new redeployment with a new service bit NODE_UAWITNESS and new compact block protocol version - doing this avoids many gotchyas which I will explain below:
Currently, segwit capable nodes advertize the NODE_WITNESS service bit and preferentially peer with other NODE_WITNESS nodes. Post activation, segwit-active nodes will then know who they should relay witness blocks to and who they should relay old style stripped blocks to. The assumption is if I am a NODE_WITNESS node and segwit has activated, then other NODE_WITNESS nodes will also be segwit activated. We cannot reuse NODE_WITNESS because when BIP149 activates, they would believe non-BIP149 NODE_WITNESS nodes were also active. Using a new service bit, and effectively starting a new deployment as if the previous deployment doesnt exist, is the most predictable and trouble free way to go about it.
Additionally, BIP149 is compatible with existing mining software by reusing the "segwit" name and deployment chainparams (it's not possible to have two deployments with the same name, one expired and one pending/active, due to how versionbits is implemented). In short, if the current segwit deployment fails to activate, we can reuse parts to maintain compatibility, while changing the bare minimum to remove any conflicts with old nodes. It's clean, predictable and easy to review.
BIP148 IS NOT BIP149
Remember BIP148 is exceptional, it's NOT what a usual UASF BIP should look like. A normal UASF if effectively activation on a predetermined date in the future (a flag day). BIP8 combines BIP9 miner signalling with a flagday if MASF does not occur.
How is BIP149 different to BIP148? So BIP148 is a UASF which can be used in two ways. (a) The economy can run BIP148 and basically force miners to signal for segwit, thus activating the current segwit deployment. Or, (b) a majority of miners, 60% or so, could run it and censor other miners who do not signal segwit, thus causing the current segwit to deploy. In method (a) a chain split will occur if any miners do not upgrade, and given the fact there are always absentee miners and pool operators, this is quite likely. It's the economy vs hash power saying "if you dont signal, your blocks will not be worth anything because we will reject them". In the case of (b) you have a majority of hashpower, who could use their majority to orphan any non signalling miners. This isn't great but it's less disruptive than (a) because there is a majority hashpower definitely opted in.
BIP149 on the other had does not guarantee a chain split since that could only happen if a miner deliberately takes action to manually create a segwit invalid block, which would be rejected by the economy. The incentives are different also, with BIP148 a chainsplit comes for free, regardless of if it lasts long or not. In BIP149, a miner would have to specifically take action to split and waste their money, which they could do at any time anyway. BIP149 is uncontroversial in the sense it is just a redeployment with guaranteed activation at the end, for a soft fork we are fairly sure people want and will upgrade to. The evidence is everywhere. UASFs deployed over a long time and a decent flagday are perfectly safe - all soft forks are enforced by nodes, even if activation is triggered by hashpower.
Anyway, we've got 8 months from now to review and think about BIP149 - it cannot be deployed until November. If you would like to show support for BIP149, feel free to add the following to your bitcoin.conf
uacomment=UASF-SegWit-BIP149 
Note you can have multiple uacomments like:
uacomment=BIP8 uacomment=UASF-SegWit-BIP149 uacomment=UASF-SegWit-BIP148 
You can find the bitcoin.conf file here
You can also just add this to a shortcut - create a shortcut (or edit the existing one you use) and add this to the end: -uacomment=UASF-SegWit-BIP149
e.g. (just add the property to the end like this):
"C:\Program Files\Bitcoin\bitcoin-qt.exe" -uacomment=UASF-SegWit-BIP149 if you are using Windows.
You can also just add uacomments as multiple command line/shortcut arguments like
-uacomment=BIP8 -uacomment=UASF-SegWit-BIP149 -uacomment=UASF-SegWit-BIP148 
Then you can check here to see how your node is signalling at https://bitnodes.21.co/ will show something like: xxx.xxx.xxx.xxx:8333 /Satoshi:0.14.1(UASF-SegWit-BIP149)/
If your node has synced and doesn't show using the link above make sure to enable forwarding of port 8333 so you accept incoming connections (if you want to that is) - in your client: go into settings / network and tick enable incoming connections and use upnp. You might have to add it to your firewall if this doesn't work. [taken from this user comment].

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 450 Full Nodes running.

Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 450 Full Nodes running.

Since every full VTC node can only serve so many clients, it's important to do your part for the Vertcoin network and run your own full node.
Q: WHAT IS A FULL NODE? A: Full nodes maintain a copy of the blockchain/ledger, distribute it to those downloading it, confirm transactions, and further spread out all of the previous functions to make the network more resilient. https://bitcoin.org/en/full-node
Q: Do I need to be a miner? A: No, you don't need to be a miner. Miners create new blocks. Full nodes simply share existing blocks (the entire VTC blockchain) with the rest of VTC wallet users.
Q: How do I run a Full VTC node on Intel NUC? A: Intel NUC Vertcoin full node installation done using Windows guide: https://github.com/vertcoin-project/VertDocs/blob/mastedocs/FullNodes/intel-nuc.md
Q: How do I run a Full VTC node? A: It's actually quite easy to do. If you run Vertcoin-QT (Vertcoin Core Wallet) on your PC/MAC desktop, keep it active in the systray. Then, make sure that you map the public port 5889 of your router to the port 5889 on the machine running Vertcoin-QT or vertcoind. For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background.
Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

Can't get more than 8 connections in bitcoin core client. Open port, maxconnections=200, nothing works.

Using Bitcoin Core v0.14.1. Port 8333 is forwarded to the correct machine, the firewall on the computer has that port open, I tested that the port is open from outside (https://www.grc.com/x/portprobe=8333), the client is configured to accept incoming connections. But it stays at 8 connections.
The only strange thing is that I have a bitcoin.conf file that has dbcache=4000 and maxconnections=200, but when I open the preferences panel it only shows the dbcache override. I thought I might have edited the wrong conf file but as far as I can tell it's the right one.
Anyone has any ideas? Am I missing something? Thanks for any help!
EDIT: I'm an idiot. Everything was working correctly, but it turns out maxconnections affects the number of incoming connections and the bitcoin-qt client only reports the number of outgoing connections, which is hard limited to 8.

Comcast drops my connection once TOR connects

Anyone else notice that their internet connection drops out when using TOR. At first I suspected a configuration setting, then spent some time looking at HW, finally I began to suspect that it may be intentional. I suspect if Comcast sees a connection to a known relay, it just resets the modem. I know they do port scans because whenever I torrent a linux distro, I get a rediculous message from them with a subject like "Warning Hackers control your network". I'm sure they see it as a public service, I just find it rather creepy. Thank goodness for VPNs.
UPDATE [Jun 25]: Been running under a bridge for last hour and that seems to work, but I hate burning a bridge someone might need just cuz comcast sux.
UPDATE [Jun 25]: I was running a hidden service which violates the AUP. It has been theorized that I got booted because the big-bother-script saw bitcoin-qt running with incoming connections through my onioin
UPDATE [Jun 26]: Started up my hidden service without a bridge today, and so far I haven't gotten the boot. Apparently P2P software is still very much in violation of comcast TOS/AUP, which sux, so screw you Comcast.
TL/DR: Comcast cuts connection when Tor spins up, buy a VPN. or burn a bridge

Lore v2 QT on Raspberry Pi

Hello,
 
To follow up to mindphuk's excellent piece on building the headless client on Raspberry Pi (https://www.reddit.com/blackcoin/comments/6gkjrw/wip_blackpi_a_stake_device_based_on_raspberry/), I thought if anyone was interested I'd show you how to get the full QT version running on the Pi on the Jessie with Pixel desktop. This works and has been soak tested for several days now on a standard Raspberry Pi 3. I have since added some coins and it stakes a handful of times a day.
 
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
 
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
 
These instructions assume you are starting from scratch with a completely blank OS.
 
Download Jessie with Pixel from: http://downloads.raspberrypi.org/raspbian/images/raspbian-2017-07-05/2017-07-05-raspbian-jessie.zip
 
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
 
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
 
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
 
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
 
sudo nano /etc/dphys-swapfile 
 
and Change the CONF_SWAPSIZE from 100 to:
 
CONF_SWAPSIZE=1024 
 
Exit nano with control + x to write out the file.
 
Then, run the following to restart the swapfile manager:
 
sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start 
 
Now, launch the browser and download the Lore 2.12 binaries for ARM here: https://mega.nz/#!k2InxZhb!iaLhUPreA7LZqZ-Az-0StRBUshSJ82XjldPsvhGBBH4 (Version with fee fix from 6 September 2017)
 
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
 
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
 
In the Terminal window, change directory to where you put the binaries, e.g.:
 
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x * 
 
That marks the binaries as executable.
 
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install 
 
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
 
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
sudo ldconfig 
 
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
sudo apt-get install qrencode libprotobuf-dev libevent-pthreads-2.0-5 
 
Now we need to install the Berkeley Database version 6.2.23. This is the version Lore v2 uses. Bitcoin still uses 4.8 which is 10 years old! This doesn't take too long.
wget http://download.oracle.com/berkeley-db/db-6.2.23.tar.gz tar -xvzf db-6.2.23.tar.gz cd db-6.2.23/build_unix ../dist/configure --prefix=/usr --enable-compat185 --enable-dbm --disable-static --enable-cxx 
 
I find this next section of the Berkeley instructions worked better just switching to root, which can be fudged by running sudo su before the rest:
sudo su make make docdir=/usshare/doc/db-6.2.23 install chown -v -R root:root /usbin/db_* /usinclude/db{,_185,_cxx}.h /uslib/libdb*.{so,la} /usshare/doc/db-6.2.23 
 
Now we're going to go up a couple of directories to where the binaries were:
cd ../.. 
 
Then run the client!
./bitcoin-qt 
 
And there you have it. Should hopefully end up looking a bit like this: http://imgur.com/a/eEHGa
 
Using the Bootstrap can save a while syncing. Download it at: https://www.reddit.com/blackcoin/comments/6b3imq/blackcoin_bootstrapdat_up_to_block_1631800
 
Place the bootstrap.dat file into the ~/.lore directory.
 
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
 
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop 
 
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None; 
 
Power usage and payback time
 
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
 
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
 
Securing your Pi
 
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
 
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
 
passwd 
 
You'll be prompted to enter the old and the new passwords.
 
Security by default
 
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
 
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
 
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable 
 
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
 
ifconfig 
 
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
 
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
 
You can query the status of the firewall like this:
ufw status 
 
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
 
Back up & Recovery
 
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
 
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
 
~/.lore 
 
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
 
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
 
In Windows, one way is to use Bitlocker drive encryption for the entire drive. You should follow the instructions here to encrypt your flash drive before your wallet.dat is on there, and don't forget the password!!
http://infosec.nmsu.edu/instructions-guides/how-to-enable-bitlocker-to-go-for-external-hard-drives-and-usb-flash-drives/
 
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale   There are almost certainly free packages with similar functionality, I have just used that one for years.
 
Either way, if you want to just make sure your USB drive is encrypted, you can do so in one-click in Finder before you put the sensitive files on it: http://lifehacker.com/encrypt-a-usb-stick-in-finder-with-a-click-1594798016
 
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
 
Recovery
 
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
 
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
./bitcoin-qt -rescan 
 
And if that doesn't do the job, do a full reindex of the blockchain:
 
./bitcoin-qt -reindex 
 
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
 
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
 
In the meantime, feel free to comment with your best practices.

Bitcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.12+, and Windows 7 and newer. Bitcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Bitcoin Core on unsupported systems. To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details. Bitcoin Core Daemon. If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core.
