Feather - free, open-source Monero desktop wallet releasing soon™

For the past year tobtoht and I have been working on the foundations of a new Monero desktop GUI called Feather for Mac OS and Linux platforms (Windows tentative) using Qt5, libwallet, QtWidgets.
The goal of this new wallet is to provide a practical, robust and easy-to-use Monero wallet for every day use. It aims to be beginner friendly, but should also cater to the needs of experienced Monero users with the addition of advanced features like coin control and multisig.
Feather's user interface is inspired by Bitcoin's Electrum wallet, but adapted to fit Monero. Feather is not a fork of Electrum, all of the UI code was written from scratch in C++ / QtWidgets.
Development began in the summer of 2019. We estimate to release a beta version in November or December.

Why

Our primary motivation is to create a wallet that we ourselves would want to use and recommend to friends. There aren't many options when it comes to non-custodial Monero desktop wallets. The CLI is an excellent tool for power-users, but is simply not an option for users that are not familiar with with the terminal. The GUI has a slick user interface, but is demanding on system resources due the use of Qt Quick.
Instead we've taken inspiration from Bitcoin's Electrum and started working on the most basic looking Monero desktop wallet one can imagine. We've gotten rid of a lot of functionality, but also added new functionality. Just focussing on the basics results in a clean, robust, and beginner proof wallet.

Privacy

In an effort to mitigate unintentional off-chain linking, we have made it harder to reuse addresses by automatically hiding used subaddresses. We find that the primary address leads uninformed users to believe that it is somehow functionally incompatible with subaddresses, or that funds sent to subaddresses can not be spent together. To encourage the use of subaddresses the primary address is hidden by default, and only used for change and coinbase outputs.
Our wallet supports advanced coin control features like freeze/thaw and sweeping a single output. In the future we may add manual transaction input selection.
There is no need to manually setup Tor to protect your traffic, Feather comes bundled with Tor. By default all traffic is routed through Tor with the exception of traffic between wallet and daemon. Wallet synchronization over Tor takes substantially longer than over clearnet, but you can optionally enable to connect to remote nodes over Tor. If your machine already has a Tor daemon running Feather can use the system daemon when instructed.
Just like in the official GUI, Feather essentially has 2 modes of connecting to the Monero network. You either host your node somewhere (localhost/LAN/internet) or we'll provide you one from a list of trusted, stable, community hosted remote nodes (like Cake Wallet). If Feather detects that it's running on Tails or Whonix it will automatically connect to a random .onion remote node.

Performance

Feather is built with Qt Widgets, providing native looks and performance. In a recent test™ a wallet with 10k+ transactions only consumed 200 MB ram (before optimizations). In comparison, the official GUI uses 400 MB before a wallet is opened.
GPU power is plenty nowadays so this hardly a problem, however, we are serious about providing an user interface that feels snappy to use. The application itself starts within 1-2 seconds on most machines (Bitcoin's Electrum is more like 4-5 seconds due to their usage of PyQt).

User experience

We have implemented Tevador's 14 word seed scheme with embedded restore height. The same function is used to derive the private view key from the private spendkey, therefore it is possible to convert the 14 word seed into a standard 25 word seed in case you want to restore the wallet using the official wallet software.
Feather connects to a websocket server over Tor to obtain miscellaneous data such as: price information, a list CCS proposals, posts on /Monero, the most recent blockheight, a list of community hosted nodes and the latest version of Feather.
The websocket server itself is open-source and self-hostable. By default Feather will connect to a server hosted by the project maintainers. The websocket connection can be disabled completely, but some functionality will be disabled/broken.
Our target audience are users who want to use Monero without too many issues and we've designed the wallet as such, with lots of convenience features, while routing it all over Tor in the background.
The native look of the application should feel familair to users as it behaves like any other program that runs on their computer. Added benefit for future contributors/developers is that it's very fast to implement/test UI components by borrowing from QtWidget's vast library. This in contrast with the Monero GUI, which uses custom QML components - a tricky and time consuming rendereframework more suited for large teams to create electron-like applications.

Additional information

Proposal

Work started early summer 2019. We still have some features to finish, prepare CI/CD, etc. As such we expect an alpha or beta release in December 2020. For this we would like the community's approval to allow the milestones defined in GUI CCS to be used for the remainder of this project, paid in full - we can use the support. Consequently all code will be licensed under the Monero Project and features/changes to libwallet or wallet2 will be committed to upstream (Monero GUI/core). Future development and releases will be maintained by dsc__ and tobtoht.

Beta testing

Idle in #feather on irc.oftc.net if you want to help beta testing in a month or so. You will need Linux, as this is our primary platform for developing the application.
Please let us know what you think in the comments. We're open to suggestions/feature requests/brainfarts.

txindex=1 server=1 question (node, rpc)

Edit: solved! Just needed to wait for indexing to catch up
Hi all I'm trying to use btc-rpc-explorer
https://github.com/janoside/btc-rpc-explorer
I have a full node via bitcoin qt. Can I use qt for block explorer?
I launch block explorer and I'm getting rpc error. The webpage states "check rpc connection info"
The github project states I need server=1 and txindex=1. Can I make qt run with these settings? I tried adding them to the .conf but how can I confirm qt is running with these options, in console somehow?
In case I can't use qt for this I downloaded bitcoind. It looks like I can start the daemon with txindex=1 and server=1 but still getting same connection problem with btc-rpc-explorer.
Do I have to do -reindex=1? Can I do that within qt? If not and I use bitcoin cli will it disrupt qt in any way?
Thanks
Edit: this is on Ubuntu

Connecting bitcoin-qt to bitcoind on local network

Hello,
I have a bitcoin node running on a headless box (bitcoind) and I would like to connect to it using bitcoin-qt on my desktop. I'm getting a little confused with the process.... does bitcoin-qt need to connect to bitcoind using RPC? Do I store my wallet file on the bitcoind box, or bitcoin-qt box?
The bitcoin node is already setup to work with an electrum server, so I already have rpcbind=0.0.0.0, rpcallowip=$ELECTRUX_IP, and rpcuserpcpassword set. I tried adding my desktop IP to rpcallowip, and setting the appropriate username/password in bitcoin-qt's bitcoin.conf, but no luck. I can see in debug.log for bitcoin-qt that the connection is rejected.

The node runs over TOR and I have onlynet=onion set in bitcoind's bitcoin.conf, but that doesn't seem to stop electrumx connecting via RPC over clearnet, so this shouldn't be an issue right?

Am I missing something here? Help would be much appreciated!

[Tutorial] Build and run your own Bitcoin node on Ubuntu 19.10

I am finally doing my part and running my own bitcoin node in a small home server.
Most guides I found online were either incomplete, outdated, or explained only how to run bitcoin-qt (graphical interface). So I built a minimalistic guide with the starting point of Ubuntu 19.10 to run the latest Bitcoin core release (v0.19.0.1) as of today.
If you have an old laptop (raspberry pi, NUC, etc even better) a reliable internet connection, and ~ 500Gb of HDD (USB external drive are just fine), you should consider running a node. It's fun, you will deepen your computer knowledge, and you will be supporting the network.

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.

How to Upgrade?

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.

cold storage compatibility issues

Hello, I have been a fan of electrum because of its offline capability. I like that I can use Bitcoin while storing my private keys on a computer that has the wifi card removed and hot glue stuffed in the Ethernet port. However it looks like maybe the electrum developers have over-promised and under-delivered in this regard. Or, maybe they simply do not have the time, energy, resources to make this work in real life.
Let me explain. I have an old-ass computer that is running Ubuntu 12 (precise), this computer has electrum 2.5.4 installed with a cold-storage wallet that has my private key.
I want to send some bitcoin from that address to a new wallet on my desktop so I can spend the bitcoin. So I installed electrum (newest version 3.3.8) on my desktop, imported the bitcoin address, and created a transaction. Then I sent the transaction to the offline computer out of band, and verified that the out-of-band transmission worked by comparing the hash of the txn file on both the offline and online machines. Then I tried to open the txn file on the offline machine with Electrum 2.5.4. Well, guess what, it didn't work. Electrum 2.5.4 printed to the console:
Traceback (most recent call last):
File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 2261, in do_process_from_file
self.show_transaction(tx)

d[inputs] = list(parse_input(vds) for i in xrange(n_vin))
OverflowError: Python int too large to convert to C long
That's pretty frustrating, the first thing I tried was to install Electrum 2.5.4 on my Desktop and try to create a new unsigned transaction with Electrum 2.5.4. However, this is a no-go because old versions of Electrum cannot connect to Electrum servers any more. So I have to try to update the Electrum on the Offline computer. But I'm not even sure if this is possible considering how ubuntu 12 it's definitely out of support at this point and the offline computer does not even have python3 installed, let alone the GTK stuff or whatever is probably required to run Electrum.
I'm starting to regret choosing a GUI-based wallet for my offline storage considering how hard it is to actually use this and how it simply melts over time... even just 5 years is is enough time to completely melt and destroy this software and make it un-usable. Time Catches All. So now I have to go out and buy a new computer that can run the updated OS, so I can install the new version of Electrum, so I can access my bitcoin.
Do you have any other ideas? Has anyone else experienced anything like this?

Crypto Faucet I use to store my mined bitcoin on, with 4.08% APR paid daily with accounts over 30k satoshi. Referral link included, I share 50% commissions with my referrals paid every Sunday if you're interested.

My referral link for the aforementioned FREEBITCO.IN: https://freebitco.in/?r=30437643&tag=redditF
I have cross referenced this post on my site: passivecryptoguides.com
Why should you sign on with me? I'm not a one off, you can reach me personally through DM or post comments. I've done most of the leg work, alleviating the trial and error process. Just follow the steps in this guide specifically in sections 7️⃣, 8️⃣, and 9️⃣.
I share 50% commissions, get a kick back on everything you earn weekly.
I trust this site, and personally have 270$ worth of bitcoin in one account with almost 500$ total including two other accounts.
Coming from Cointiply? Well, as a heads up, you're not actually holding any BTC. I suggest what you earn you HODL in FREEBITCO.IN.

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.📝
Current rewards and probability with every hourly roll.
(.002$) -> 98.85%

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.

Litecoin Support Phone Number +1(855)3008358 (Toll-Free Number)

Litecoin was released in October 2011 in the form of a client with an open source code on the Internet hosting GitHub by Charles Lee, a former Google employee. The crypto currency works according to the MIT/X11 license, which allows anybody to execute, modify and copy software as well as to distribute any modified copies. It was a fork of the Bitcoin-Qt client, differing primarily by having a decreased block generation time, increased maximum number of coins, different hashing algorithm, and a slightly modified GUI.
The Litecoin exchange rate gave a jump in November 2013: the capitalization of crypto currency exceeded 1 billion dollars.

Advantages and Disadvantages of Litecoin

Litecoin

Litecoin (LTC) is a decentralized cryptocurrency, a fork of Bitcoin intended by its designers to be more feasibly mined using consumer-grade hardware. Litecoin is a peer-to-peer crypto currency that was developed on the base of Bitcoin and has an open source code. Unlike Bitcoin, the Litecoin blockchain is able to process a greater number of transactions.
The creator of Litecoin – Charlie Lee, a former employee of Google – took the Bitcoin source code as a basis and created a crypto currency that needs 2.5 minutes to generate a block – this is 4 times faster than Bitcoin.The full emission of Litecoin makes out 84 million coins, which is also 4 times more than of Bitcoin. The start reward for a block made out 50 Litecoins, and now it is 25 Litecoins.

What are your censorship stories that bitcoin would fix

I saw another post that I thought was asking for censorship stories, but it was just a different type of complaint, so I thought to make this post.
So... What are some stories you'd be willing to share that woke you up to how much centralized censorship there is today, and why bitcoin might help.
I'll start:
2015, I wanted to check out bitcoin so I got some from a faucet and downloaded bitcoin-core and the blockchain. Few days later I got a letter from Comcast (my ISP) saying that they recognized suspicious traffic on my MAC and suggested I call support to have a tech come out and run a virus scan. I ignored it, but it prompted me to log into my ISP account, which I never do. Sure enough I had a stack of emails from Comcast to my ISP email address saying the same thing. Turns out they were routinely doing port scans on my network looking for open ports. When I opened my NAT firewall for bitcoin-qt they saw this as "suspicious traffic".
Not really "censorship" but definitely creepy.
2016, getting kinda freaked out by the previous, I decide to run my client over TOR. This was on a linux box so I no longer had the blockchain. So I set it up and start pulling down blocks and I'm now satisfied that my node is reachable without having to punch a hole through my NAT or get nasty letters from Comcast. Then all of the sudden my connection drops. Assuming it's just crappy internet I don't think about it for the rest of the week. Weekend comes and I have some free time so I fire up my linux box and my tor node then boom.... my connection drops. Turns out every time I fired up my tor node they would "re-provision" my cable modem. Filed a shit-ton of issues, letters and social media posts.
End result was that the directed me to their terms-of-service which explicitly prohibit the use of "peer-to-peer" software or running any internet "servers" on their service.
2018, My previous encounters got me interested in Tor, I2P, and other types of networks. I wrote a series of posts about it. Since all my spare money goes into DCA I decided to go with a free dynamic-dns service for a static hostname. Eventually, since tons of scammers use the same free dynamic-dns service, both reddit and facebook have a site-ban on any URL linking to it. Luckily my gh-pages link does a 301 redirect so I can link to it indirectly here: https://brianddk.github.io/darkweb . For fun try pasting the URL it redirects to in a reply post and you will find the site automod kick in and remove it. Won't affect your user account though.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

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.

Bitcoin Full Node on Ubuntu 18.04

Need help! I feel like I am missing something stupid small here. I am trying to run a Ubuntu based Bitcoin Full node. I am trying to run this on on a VM Box in VMWare ESXi 6.5. I have tried Ubuntu Desktop and Server 12.04, 14.04, 16.5, and 18.04. The VMWare box has been giving 6gb of ram, 1TB of storage, and 4 CPU Cores. All of them seem to have the same problem. They freeze my entire box. Usually, the freeze occurs while syncing headers but could happen even while trying to connect to neighbors.
I uses these scripts to install Bitcoin Core:
sudo apt-add-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install bitcoin-qt
Has anything heard of this before? I feel like I am late to the party but I cannot find a way around this.

Trezor and privacy

Hi All,
Maybe someone can help me out.
I have a Trezor. Now, I have my private seed safe, which I like.
However:
My privacy is not safe. Because when I use the Trezor Wallet, my local browser is connecting the (bitcore) servers of Trezor. So my public key's are exploted. So I am not using my own trustable Bitcoin full node.
I tried to install my own Bitcore server, but I can not get that worked.
I tried to run Etherum Personal Server (EPS) to connect Etherum to. In Etherum I can use my Trezor. That works. But i do not like this, because it is a difficult setup. Also EPS is in beta.
I have three questions:
  1. Is it true that when I use the Trezor Wallet, Trezor will know my transaction history and public addresses I am watching?
  2. Is there another way I can solve this?
  3. Ehm.... am I the only one having this problem? Are my expectations to high? I expect, when I buy a product like Trezor, it will be totally safe, using the strengths of Bitcoin and so it is possible with this product to use my own full node. Is it strange when I say this is not a mature part of bitcoin (having the private key in a hardware wallet and using your own bitcoin full node)
It looks like I better can use the official bitcoin wallet (bitcoin-qt), because that one I can trust, and throw away my Trezor. I understood bitcoin-core it is a HD wallet already.
Thanks

What is up with all these Bitcoin devs who think that their job includes HARD-CODING CERTAIN VALUES THAT ARE SUPPOSED TO BE USER-CONFIGURABLE (eg: "seed servers")?

Recently, the developer of SegWit2x / BTC1, Jeff Garzik, caused some controversy by hard-coding the "seed servers" which Bitcoin uses to first start hunting for "peers".
Worse than that: apparently one of the "seeds" is a company he started, variously named Chainalysis / Skry / Bloq - which apparently specializes in de-anonymizing Bitcoin transactions and performing KYC/AML - and which also has apparently entered into agreements with Interpol.
Seriously, WTF???
This is what "Bitcoin devs" still consider to be part of their "job" - hard-coding parameters like this, which affect everyone else on the network - and which could easily be "exposed" to be made user-configurable - instead of being baked into the source code and requiring a friggin' recompile to change???
This recent event has refocused attention on the fact all these past years, most of these seed servers in "the" existing (legacy) client running on most of the network have _also been hard-coded - to domains under the control of "devs associated with Blockstream".
I don't like the list of seed servers in Bitcoin Core
Pieter Wuille - does not support BIP148 - works for Blockstream
Matt Corallo - does not support BIP148 - works for Blockstream
Luke Dashjr - supports BIP148 - works for Blockstream
Christian Decker - supports BIP148 - works for Blockstream
Jonas Schnelli - supports BIP148
Peter Todd - supports BIP148 - worked for Samson Mow who works for Blockstream
https://np.reddit.com/btc/comments/6nd50h/i_dont_like_the_list_of_seed_servers_in_bitcoin/
The corporate takeover of bitcoin illustrated in 1 commit
In The corporate takeover of bitcoin illustrated in 1 commit a user complains that btc1 changing the seed servers to servers run by some companies (see commit) equals a "corporate takeover of bitcoin". I never really took much care who runs these seed server, although they do posses a certain power over the network as correctly pointed out by P. Todd in the same thread:
...and the key thing with that is being able to control what nodes a node connects to can be a very powerful tool to attack new nodes, as it lets you prevent a node from learning about the valid chain with the most work.
[...]
4 out of 5 people running the bitcoin networks seed servers are directly associated with Blockstream!
I don't even believe that Blockstream is actually plotting an evil, forceful takeover of bitcoin using the seed servers. However it beautifully counteracts Adam's "decentralization is everything" arguments. What is most troublesome to me, is that this simple information is not allowed to appear on r\bitcoin at all.
https://np.reddit.com/btc/comments/6n8vqc/the_corporate_takeover_of_bitcoin_illustrated_in/
Seriously?
Bitcoin is almost 9 years old - and most people are still running clients which use hard-coded values (which require an inconvenient recompile to reconfigure) for the "seed servers"??
Maybe this is, in some sense, part of the reason why people like BlueMatt and Luke-Jr and Pieter Wiulle think they can lord it over us and tell everyone else what to do? ...because they have quietly (and unfairly / incompetently) hard-coded their own friggin' server domain names directly into everyone else's client code, as our "seed servers"?
Is the low level of "quality" we - as a community - have become accustomed to from our devs?
Do other clients (Bitcoin Classic, Bitcoin Unlimited and Bitcoin ABC) also gratuitously hard-code their "seed servers" like this?
Here's a post from a year ago regarding "seed servers" in Classic:
How come "classic" uses the same alert keys/DNS seeds as Core?
https://np.reddit.com/btc/comments/44atsp/how_come_classic_uses_the_same_alert_keysdns/
Meanwhile, here's the main question:
Why are any "serious" Bitcoin clients still "gratuitously" hard-coding any values like this?
Why has our "ecosystem" / "community" not naturally evolved to the point where we have some public "wiki" pages listing all the "good" (community-recognized, popular) seed servers - and every user configures their own client software by choosing who they want from this list?
(Maybe because we've been distracted by bullshit for these past few years, fighting with these very same devs because they've refused provide any support for users who want bigger blocks?)
What would users have to do if (God forbid) something were to happen to the servers of those 4-5 seed servers which are currently hard-coded into nearly everyone's clients?
In that situation (assuming some "new" seed servers quickly appeared) people would be have two options:
  • Edit their C++ source code and download/install a (trusted, verified) C++ compiler (if they don't already have one), and recompile the friggin' code; or
  • Wait until new binaries got posted online - and download them (and verify them).
Seriously?
This unnecessary "centralization point" (or major inconvenience / bottleneck) has been sitting in our code this entire time - while these supposedly knowledgeable devs keep beating us over their head with their mantra of "decentralization" - which they have actually been doing so little to maximize?
Psycho-Socio-Economic Side Bar
Serious (but delicate/senstive) question: How many of these "devs" have developed (possibly unconscious?) behaviors in life where they try to make users dependent on them?
"Vendor lock-in" is a thing - a very bad thing, which certain Bitcoin devs have exhibited a tendency to inflict on users - in many cases due to rather obvious (psychological, social, and/or economic) reasons.
We should gently (but firmly) reject these tendencies whenever any dev exhibits them.
Our community should expect and demand an accessible, user-friendly interface for all user-configurable parameters - to maximize decentralization and autonomy
  • In "command-line" versions of the client program, these kind of parameters should be:
    • in a separate config file - using some ultra-simple, standard format such as YAML or JSON
    • also configurable via options (eg, --seed-server) upon invocation on the command-line
  • In GUI versions version of the client program (using some popular cross-platform standard such as Qt, HTML, etc.) these kind of parameters should be exposed as user-configurable options.
Yes, these user-configurable values for things like "seed servers" (or "max blocksize") could come pre-configured to "sensible defaults - so that the software will work "out of the box" (immediately upon downloading and installing) - with no initial configuration required by the user.
Yes: Even the blocksize has always been user-configurable - but most users don't know this, because most devs have been hiding this fact from us.
Three recent posts by u/ForkiusMaximus explained how Adjustable-Blocksize-Cap (ABC) Bitcoin clients shatter this illusion:
Adjustable-blocksize-cap (ABC) clients give miners exactly zero additional power. BU, Classic, and other ABC clients are really just an argument in code form, shattering the illusion that devs are part of the governance structure.

Adjustable blocksize cap (ABC) is dangerous? The blocksize cap has always been user-adjustable. Core just has a really shitty inferface for it.

Clearing up Some Widespread Confusions about BU
https://np.reddit.com/btc/comments/602vsy/clearing_up_some_widespread_confusions_about_bu/
Note about Bitcoin ABC vs Bitcoin Unlimited:
There is a specific new Bitcoin client called Bitcoin ABC, which functions similar to Bitcoin Unlimited - with the important difference that Bitcoin ABC is _guaranteed to hard-fork to bigger blocks on August 1_.
(Please correct me if I'm wrong about this. Documentation for the behavior of these various hard-forks is currently still rather disorganized :-)
All serious devs should be expected to provide code which does not require a "recompile" to change these "initial, sensible" default parameters.
I mean - come on. Even back in the 80s people had "*.INI" files on DOS and Windows.
Nearly all users understand and know how to set user-configurable values - for decades.
How many people are familiar with using a program which has a "Preferences" screen? (Sometimes you may have to close and re-open the program in order for your new preferences to take effect.) This is really basic, basic functionality which nearly all software provides via a GUI (and or config file and/or command-line options).
And nearly all devs have been offering this kind of functionality - in either command-line parameters, config files, and/or graphic user interfaces (GUIs).
Except most Bitcoin devs.
The state of "software development" for Bitcoin clients seems really messed up in certain ways like this.
As users, we need to start demanding simple, standard features in our client software - such as accessible, user-friendly configurability of parameter values - without the massive inconvenience of a recompile.
What is a "Bitcoin client"?
After nearly 9 years in operation, our community should by now have a basic concept or definition of what a "Bitcoin client" is / does - probably something along the lines of:

A Bitcoin client is a device for reading (and optionally appending to) the immutable Bitcoin Blockchain.

Based on that general concept / definition, a program which does all of the above and also gratuitously "hard-codes" a bunch of domain names for "seed servers" is not quite the same thing as a "a Bitcoin client".
Such an "overspecialized" client actually provides merely a subset of the full functionality of a true "Bitcoin client", eg:
  • An "overspecialized" client only enables connecting to certain "seed servers" upon startup (in accordance with the "gratuitous opinion" of the dev who (mis)translated the community's conceptual specifications to C++ code)
  • An "overspecialized" client only enables mining blocks less that a certain size (in accordance with the "gratuitous opinion" of the dev who (mis)translated the community's conceptual specifications to C++ code)
One of the main problems with nearly all Bitcoin clients developed so far is that they are gratuitously opinionated: they "gratuitously" hard-code particular values (eg, "max blocksize", "seed servers") which are not part of the whitepaper, and not part of the generally accepted definition of a "Bitcoin client".
This failure on the part of devs to provide Bitcoin clients which behave in accordance with the community's specification of "Bitcoin clients" is seriously damaging Bitcoin - and needs to be fixed as soon as possible.
Right now is a good opportunity - with so many new Bitcoin clients popping up, as the community prepares to fork.
All devs working on various Bitcoin client software offerings need to wake up and realize that there is about to be a major battle to find out which Bitcoin client software offering performs "best" (in the user-interface sense - and ultimately in the economic sense) at:

reading (and optionally appending to) the immutable Bitcoin Blockchain

The Bitcoin client software offerings which can optimally (and most simply and securely :-) "satisfy" the above specification (and not merely some gratuitously overspecialized "subset" of it) will have the most success.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.
