Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Play Online Poker with Bitcoins

Play Online Poker with Bitcoins
Bitcoin (or BTC) is a decentralized virtual currency which is traded in the same way as currencies or bonds, except that for the storage of Bitcoins it is necessary to download an “electronic wallet”. According to Bitcoin there is no person, company or government that controls Bitcoin, so it requires users for its operation and the greater the demand, the greater its value. One of the main attractions of Bitcoin is its possible anonymity which allows the user to buy, pay and sell products and services without the intervention of any bank or financial institution.
Best Online Casinos to Play Bitcoin Poker of October 2020
In its beginnings, in 2008, Bitcoin did not obtain great popularity, but little by little it began to be adopted by more users and companies. It was in 2011 that the newspapers began to read about Bitcoin, since then companies of great international impact have begun to open their doors to transactions with Bitcoin, some of these companies are: Dell, Overstock and Microsoft.
The increasing adoption of Bitcoin by multinational companies spurred a reaction from government entities, with each country taking very different actions. In August 2013, the German Finance Minister declared Bitcoin as a "unit of account" which can be used for private transactions, which allowed Germany to control this virtual currency. In December 2013, the Chinese government prohibited banks and financial institutions from transacting with Bitcoins due to security and transparency issues. This government action caused a considerable drop in the value of Bitcoin since users in this country could not change their Bitcoins to the local currency. The United Kingdom and the European Union have also recognized Bitcoin as a type of currency and every day this cryptocurrency is accepted by more countries. However, each specific case must be analyzed, for example: in the case of the United States; Bitcoin is not considered a digital currency but rather a taxable product.
Buying Bitcoins for the first time can seem a lot more difficult than it actually is. There are many methods to acquire Bitcoins, the most practical is to acquire them directly from an exchange house or Bitcoins exchange houses. Their names denote their difference, in exchange houses you will go to a provider who will sell you Bitcoins for your local currency, while in exchange houses you interact with other users to exchange Bitcoins for real money. Bitcoins transactions can last from 10 minutes to several hours and are made through a Bitcoin address (similar to mail methods, only the address in this case is a series of numbers and characters), once you receive the transfer you must move your Bitcoins to your electronic wallet before you can use them.
In short, that's how easy it is to use Bitcoins:
· Bitcoin is a virtual currency that is stored in an electronic wallet.
· The value of Bitcoin is decentralized so it fluctuates depending on its demand.
· You can make a Bitcoins transfer in seconds and its verification takes about an hour.
· Once a Bitcoins transfer has been made, it cannot be reversed
· For the most part, Bitcoins transactions are not subject to fees or commissions.

Sites to play online poker with Bitcoins
Online poker sites have become more popular every day and since the use of Bitcoin is anonymous, decentralized and more or less instant transfers, online casinos have recognized in this cryptocurrency an excellent potential to attract new customers.
The way Bitcoins are used to gamble online divides casinos into two categories: exclusive Bitcoin poker sites and online casinos that accept Bitcoin. So, what is the distinguish between using an online casino that accepts Bitcoins and using a Bitcoin casino to play poker?

https://preview.redd.it/wo0is3x12wu51.png?width=621&format=png&auto=webp&s=b733c7964f58ba0441de2f060fed7aaf1dbfe4ed
Differences between Bitcoin poker and poker sites that accept Bitcoins
There are several differences between using an online casino that accepts Bitcoins and a Bitcoincasino, here are the most important ones:
The great differentiation between these types of online casinos will be the total offer of payment methods to enter or withdraw funds from your casino account, Bitcoin casinos do not accept other payment methods other than Bitcoin transfer, while traditional online casinos They will offer you other payment options such as a bank account or PayPal.
The expenses for using exclusive Bitcoins casinos are minimal and normally there are no fees for withdrawal of funds, contrary to the case of online casinos that accept Bitcoins as one of their payment methods since they most likely will charge you some commission.
Another great advantage of choosing Bitcoin casinos over online casinos is anonymity since you will not need to link your email or personal data to create an account. In addition to the convenience that this anonymity provides, it also streamlines the transfer process in relation to online casinos that require documentation. You should consider that this anonymity also makes Bitcoin casinos vulnerable to security problems with other users.
The game offer does not vary much between a Bitcoin casino and a traditional online casino, the most popular are: poker, roulette, slots and dice. Some small Bitcoin casinos do not turn to typical gaming providers like Playtech and Bets off as they tend to look for smaller providers that you may not have seen before.
Some of the most relevant Bitcoin casinos are: PokerStars, SWC Poker, Bitcoin Casino and Bit casino.
Pros of using Bitcoins when playing online poker
Transfer money to and from your online casino account
The requirements are basically the same as those of any traditional form of payment, of course you must have the electronic wallet software to use Bitcoins, but remember that withdrawals with this cryptocurrency they are usually much faster.
User anonymity
This advantage applies or not depending on the online casino you use, if when you sign up they only ask for information about your Bitcoin account then you will enjoy complete anonymity, however if you need to fill in personal or banking information to register at the casino then this benefit will not apply on that platform.
American users can use Bitcoin
Since Bitcoin is not recognized in the United States as a currency, it can be used as a means to enter and withdraw funds from an online casino account, remember that in the United States the laws vary a lot from one state to another so if you are an American user make sure you know the laws of your state in relation to online gambling before registering on a platform.
The double bet with Bitcoin
Many players opt for Bitcoin to place their bets since there is the possibility of winning some money depending on the exchange rate of Bitcoin when it comes to changing it to their local currency. This is why when used as a payment method for an online casino account, it is considered a double bet.
Best Rake backs
It is normal for Bitcoin casinos to offer better rake backs to their users since their expenses when using Bitcoin as the only payment method are lower, however this applies only to exclusive Bitcoin online casinos.
Cons of using Bitcoins when playing online poker
Where there are advantages, there are also disadvantages, here are the main cons you should consider when betting with Bitcoins.
Bitcoin-exclusive online casinos are sites without regulation or oversight
In the absence of a regulatory entity, it is hard to believe the promise of these casinos to use random platforms and take care of your funds. You must be much more careful when choosing an exclusive Bitcoins casino than a traditional online casino, the reputation and opinion of other players will be very important when choosing a Bitcoin Casino.
Another factor that you should take into account is that the lack of regulation of gambling with Bitcoin does not mean that you are exempt from following the gambling regulations of the place where you live, especially in the case of the United States, where the government has previously intervened in activities of bets regardless of the means of deposit or withdrawal of funds from the companies.
The fluctuating value of Bitcoin
The value of Bitcoin can vary both upward and downward. Its value can change in a matter of hours, and the behavior of its value is not so similar to that of currencies such as euros, dollars, pounds or pesos, but is more similar to the behavior of products such as oil, gold or wheat,
Relative anonymity of Bitcoin
While it is possible to register to exclusive Bitcoin poker sites without giving personal information, the use of Bitcoins can be traced through the blockchains to a personal account.
Lack of support from financial institutions
Being a decentralized currency, Bitcoin is not backed by financial institutions or government, which gives you less support as a user. If there were to be a problem with the Bitcoins system, there would be no government intervention as would happen in the case of a bank. Of course, you should consider that it is thanks to this lack of intervention that transfers with Bitcoins do not charge fees or commissions.
Being a virtual currency it is susceptible to cyberattacks.
While the programming behind the Bitcoins System is sophisticated, so are the hackers' systems. In 2013, the UK Crime Agency reported that several users of this cryptocurrency had been victims of cyber extortion, after receiving an email their computer was infected with a virus and later they were sued for some bitcoins to repair the virus on their computers. Unfortunately there are more cases like this, in Europe a payment provider lost more than a million dollars after a cyberattack.
All transactions are final
Remembering that there is no intervention by financial institutions, it becomes evident that it will be difficult to file a dispute in the event of a transfer error, so you will have to be much more careful.
conclusion
Playing poker online is a game of both chance and strategy. For some bettors it is exceptionally alluring to utilize Bitcoins since they have the chance of expanding their benefits as indicated by the Bitcoin swapping scale.
For many, traditional online casinos play poker with bitcoin will continue to be the best option due to the reliability and regulation of their transactions.
What cannot be denied is that the use of Bitcoins grows day by day and in the world of online poker as in any cyber activity you must consider the most innovative and practical solutions that there is for you.

Bitcoin vs. Credit Card Transactions: What's the Difference?

Bitcoin vs. Credit Card Transactions: An Overview

Most people have a credit card they can use to pay for things. But some also have bitcoin at their disposal. Which one should people use, and when, to maximize their assets?

Bitcoin Transactions

Satoshi Nakamoto, the inventor of bitcoin, titled his original white paper on the subject "A Peer-to-Peer Electronic Cash System." This description touches on the core differences between bitcoin and credit card transactions.
Bitcoin payments are analogous to wire transfers or cash transactions, where payment is "pushed" directly from one party to another, without going through another financial institution. Payment processing is executed through a private network of computers, and each transaction is recorded in a blockchain, which is public. Bitcoin is based on peer-to-peer technology and relies on the blockchain and the cryptography securing it, without any third-party oversight.
When making a bitcoin transaction, it is not necessary to provide personal identification, such as your name and address.

Credit Card Transactions

By contrast, credit card transactions entail the buyer effectively authorizing the seller to "pull" a payment from their account, passing through financial intermediaries in the process. For example, a typical Visa transaction involves four parties: the merchant, the acquirer (the financial institution that enables payments to the merchant), the issuer (the cardholder's bank), and the individual cardholder.

Key Differences

Bitcoin transactions are made using an anonymous alphanumeric address, that changes with every transaction, and a private key. Payments can also be made on mobile devices by using quick response (QR) codes.
While credits cards are stored physically in a wallet, bitcoin transactions are sent to and from electronic wallets, which can be stored on your computer, smartphone, or in the cloud.
Bitcoin transactions are irreversible and can only be refunded by the receiving party—a key difference from credit card transactions that can be canceled. This means there are no charge-backs for merchants when taking payment via bitcoin. A charge-back is the demand by a credit-card provider for a retailer to cover the loss on a fraudulent or disputed transaction.
Bitcoin merchants also save on credit card fees that can range anywhere from 0.5% to 5%, plus a 20 to 30 cent flat fee for each transaction made. Bitcoin payments can be sent and received at a very low cost or none at all, as bitcoin fees are based on the amount of data sent.
For merchants, the advantages of receiving bitcoin are obvious. Payments made using the virtual currency save substantially on processing fees and eliminate the risk of charge-backs. For shoppers, the advantages of paying with bitcoin include greater simplicity in placing the transaction, user anonymity, no interruptions from intermediaries, and very low transaction fees. (For example, your account being frozen as a result of a fraud alert).
Credit cards offer important beneficial features, such as the ability to borrow money, protection against fraud, reward points, and vastly wider acceptance among merchants. While a few major retailers, including Overstock.com (OSTK) and Newegg, have started to accept bitcoin, most have yet to make it a payment option. However, using credit cards carries the risk of incurring late fees, interest charges, foreign transaction fees, and potentially adverse effects on your credit score.

HELP: Website where you can buy ANYTHING with bitcoin (just insert link)?

Hey,
I am sure I've seen this type of website before. Where you just submit a link to any shopping website, along with your address details => a human will connect with you via chat => give you payment details for cryptocurrency/bitcoin and they will do the card payment thats required.
Please help me out here. Googled but cannot find it. Thanks in advance!

Edit: Was a bit unclear. I am not looking for a website that offers every type of product like overstock.com, purse.io etc.
"Buy anything" as in you could submit any link, to any shopping website, and pay with crypto to a "personal shopper" that handles the card transaction for you.

Become a Captain of Industry - Brute forcing the blockchain for fun and profit

Bitcoin Micro Collider Project link here
I stumbled across a project on Github which allows anyone to use their PCs to try and brute-force keys on the bitcoin blockchain. The tool runs in Java with a simple desktop interface.
The project includes a sample list of around 580k bitcoin addresses containing at least 0.5 BTC. If a match is discovered, the interface informs the user and saves the key/address pair to a text file.
On my 8+ year old backup PC I can check around 1 billion address/key combinations per day.
The odds of successfully matching an address are mind-bogglingly slim but greater than zero. Instead of using your CPU idle time to cure cancer or support other scientific endeavors - why not try to liberate some bitcoins? Just imagine how much garbage you could buy off of Overstock.com with more than $1 billion in bitcoin...

Ravencoin will be featured in my first official newsletter. Anything I should add?

I run a short weekly newsletter recommending lower cap coins for people to take a look at.
(If you're interested you can check out The Weekly Coin here, but honestly no pressure!)
Tl;dr: I've been in this space for over half a decade as a investor and dApp developer. I've amassed email addresses of people looking for recommendations on good low cap coins to take a look at. It started out with my brother then my Dad and grew from there. Instead of BCCing everyone I've now created an official newsletter and Ravencoin will be my first official recommendation.
As this is my first official newsletter (I'm a bit nervous 😬) I wanted to make sure I consulted with Ravencoin to make sure I touch on the most important points.
Here is the newsletter:

It's no surprise that Ravencoin is the first cryptocurrency I'd pick, it's a coin that many people have been raving about. I'll see myself out.
"Ravencoin (RVN) is an open source, fairly mined proof of work (POW) project focused on enabling users to issue assets and securities on a secure and decentralized blockchain. Cypher punk philosophy. No ICO. No pre-mine. No masternodes." — Ravencoin
Ravencoin is decentralized meaning there is no owner or CEO, their Github is very active and the core team is funded by Medici Ventures which is a subsidiary of Overstock.com. Ravencoin is a cryptocurrency that does one thing and does it well.
Overview
- CoinMarketCap Rank: 44
- Current Price: $0.026592
- Market Cap: $149,809,826
- Max Supply: 21,000,000,000 RVN
- Where to buy RVN: DigiFinex, Binance, Upbit, CoinEx
Development Frequency: Very Active averaging 1000 commits a year. Currently 5 issues are open and 586 issues are closed.
If Bitcoin is for money Ravencoin is for tokenizing assets. Many coins tout getting it right but it seems as though Ravencoin has gotten it right. I'll be watching Ravencoin and I'm very interested in what they bring to the table.

Anything I should add or subtract? Let me know what you guys think!

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
Some great introductions for new users are My first bitcoin, Bitcoin explained and ELI5 Bitcoin. Also, the following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Also have to give mention to Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series. Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute. Bitcoin statistics can be found here, here and here. Developer resources can be found here, here and here. Peer-reviewed research papers can be found here. Potential upcoming protocol improvements here. Scaling resources here. The number of times Bitcoin was declared dead by the media can be found here (LOL!), and of course Satoshi Nakamoto's whitepaper that started it all! :)
Key properties of bitcoin

Where can I buy bitcoins?

Bitcoin.org, BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash

Spectrocoin
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Samouari BreadWallet Electrum
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor

Welcome to the Bitcoin community and the new decentralized economy!

To Vitalik and other ETH Devs, GPU Miners need you and you need GPU Miners (PoW/ProgPoW)

This is directed towards u/nickjohnson, u/vbuterin, u/5chdn and other ETH Devs.

Edit: Proof of ProgPoW: https://gangnam.wattpool.net/#/account/0x445c466856266f8a609f87fdc6b0aaeb274d203f
Initial testing is seeing 8.8-10.15mh/s on RX480 and 3.8-4mh/s on RX460. Will include write-up soon, Newest ETH-Miner release!

Let me start this by saying, I mined my first BTC before it was even $100 or well known. BTC Mined. That was my first foray into the PoW mining scene. I had a lot a fun doing so. I enjoy building computers, testing equipment, fixing problems. It's literally my everyday job as an IT Hardware Analyst for a company.

I had to put down my mining on GPU dreams due to ASICs overtaking the networks of both BTC and LTC. I gave up on crypto as a hobby. Why bother? I don't want an ASIC in my house. There's no fun in tuning an ASIC, cannot change out components, upgrade it, etc. Then in 2017 I heard a whisper of GPU mineable coin that was ASIC resistant. It was called Ethereum. It was posed to be the next "Apple" with great innovations. At first I was beset by previous failures of GPU mineable coins getting overtaken by ASICs. Eventually with some discussion to my friend we built our first GPU mining rig in June of 2017. I got into Ethereum by mining it.

Now ASICs run rampant through most of the top 100 Cryptocurrencies. The current outlook, regardless of the bear-market pricing, looks bleak. I want to appeal to Vitalik, Nick, and the other Ethereum developers. It was GPU miners you had in mind when you created the Ethereum network and not ASICs. Vitalik made the best effort of a ASIC-Resistant algorithm. It latest for years but it's a cat and mouse game. Continued development of ASIC-Resistant algorithms needs to continue, not fall by the wayside. u/AndLan u/ohgodagirl, Mr If, and others have poured non-paid work into ProgPoW and getting it working on the Ethereum network because they want to see Ethereum succeed.

ASICs are now on the network, ProgPoW is a solution, and we need YOU DEVELOPERS, To stand with US, THE MINERS! Together lets push Ethereum forward to #1!

The Developers and GPU Miners need a symbiotic relationship. GPU Miners are NOT against you! You should not be against us! We need to stand together to make Ethereum strong and succeed, not become Bitcoin, which as even in Ethereum's whitepaper you understood it became fairly centralized.
However, this mining algorithm is vulnerable to two forms of centralization. First, the mining ecosystem has come to be dominated by ASICs (application-specific integrated circuits), computer chips designed for, and therefore thousands of times more efficient at, the specific task of Bitcoin mining. This means that Bitcoin mining is no longer a highly decentralized and egalitarian pursuit, requiring millions of dollars of capital to effectively participate in.

In regards to Centralization Mr If, made an excellent argument last Dev meeting, for ProgPoW which I shall reiterate/paraphrase here for everyone on Reddit.

PoW is geared towards industries of scale. This is why ASICs typically become the dominate force, because the ASIC manufactures have the capital, investment, and industry to produce them at a low cost. Thus they reap the PoW rewards. Hence why all PoW tends to go towards ASIC. They can decide to sell ASIC and recoup cost plus profit or keep mining with that equipment. Making ASICs egalitarian. ASIC manufactures decide, not the miner communities, what they do with the ASICs. You pay to play and you must be first.
ProgPoW takes the same approach but changes who the industry is, instead of Bitmain/Innosilicon it is AMD/Nvidia. These two companies are industrial level manufactures and have the ability to produce on a scale to support PoW(Just look at all the overstock of Nvidia 1000 GPUs). In this sense we are trading one(ASICs) for another (ASIC-GPUs). We as PoW miners must use Nvidia/AMD GPUs to support the network. Because it is the commodity hardware mass available to everyone. ASICs ARE NOT commodity hardware and ARE NOT mass available to everyone. Changing from Eth-hash to ProgPoW changes the players in the game and chooses the lesser two evils (AMD/Nvidia).

ProgPoW is not stricitly an Algorithm to replace Eth-hash but a has various "buttons" and "knobs" to tune. hence why its called Programmable! Ill let an Eth-miner Dev explain it...
-Andrea LanFranchi (EthMiner Dev)
ProgPoW is not strictly an Algo, it is a finite set of basic operations. ProgPoW is to be considered more of a process which creates variants of the algo every specified interval. Due to this there is no concept of ProgPoW as an immutable algo like Eth-hash. It tune-able and can dial various "knobs" that allow the creation of large number "definition sets" which again due to the deterministic randomness create an infinite number of algo changes.
ProgPoW creates a new search kernel every 50 blocks. Every 50 . blocks the gpu receives a completely new and different kernel from the previous which causes hashrate to change. In ProgPoW there is no fixed and constant hashrate for GPUs. You have to take into account averages across multiple periods to get the best out of the hardware. Variances are from 8-9%.

I personally supported the Network at $400, $180, $1400 and still support it now $100. I supported throughout the uncertainty of the Iceage and delays. Ethereum is still a PoW coin! ONE OF THE BEST! It's what made ethereum great! The project has excellent idea's of smart contracts and Dapps. On top of all is a massive GPU networking supporting it. Throughout 2017 there were no ASICs(That we know of) yet the ethereum network grew. What helped make Ethereum blossom was the miners and the mining community.

I am personally invested into Ethereum want to see it succeed, I'm personally invested in PoW GPU mining, and want to see it succeed. I will invest my own time and money, being a GPU miner, into seeing that ProgPoW testnet gets fully scrutinized, put through it's paces to ensure that it is a fit for Ethereum and minimize problems. I plead, beg, and invite all other GPU miners to do so. If we want change we as miners must show through hashpower on the testnet, that we are pushing forward with ProgPoW. Throw a single GPU, a Rig, whatever you can spare or muster for ProgPoW testnet.

I can and am more than willing to help anyone setup the necessary files, miners, etc needed to get mining on the test network.
Right now you can download the ProgPoW Miner(Updates are constant) And Ethermine is in full support.
Ethminer -P stratum://(ProgPoW Test Address)[[email protected]](mailto:[email protected]):4444 -A progpow

Let's make a Decision together on ProgPoW. Miners are in majority support of ProgPoW and 100% support of kicking ASICs of the network(Look at Ethermine's twitter poll). GPU miners supported you, helped build your network, not investors, not ICOs. At the very heart of Ethereum beats the GPU. Operating that GPU is a typically an enthusiast, hobby miner, and a believer in Crypto.

*Edit:*PoW is the known best way to distribute token "fairly", yet everyone hates it and wants PoS? What happens when large ASIC manufacture and centralized parties mining with ASICs earn more tokens than anyone else? Wouldn't that lead to centralization in PoS? Ethereum is on PoW BECAUSE it needs it! And because Ethereum needs PoW, it needs GPU miners, and to stay decentralized to PoS and in PoS it needs to keep GPUs miners on board.

Vitalik, Nick, and others, a time-line needs to be set, ProgPoW needs to be in the Agenda continually, discussed throughly, until it's launched on the main network. I will personally come chat, debate ideas, with any of you! Civil discussions are important!

Overstock Bitcoin Refund - Positive report

Hi guys, just wanted to quickly share an experience I just had.
Made a significant purchase >$1000 on Overstock.com, saw the Bitcoin payment option, and though "why not?" I'm an enthusiast and it seemed like a good idea to make my first true blue bitcoin transaction for goods/service.

As soon as I shipped the Bitcoin, a red screen came up saying: There was a problem with your order, it has been cancelled, please call customer service, etc. ....But the bitcoin was gone!

Called them, waited 2 mins, talked to a nice rep who had very little understanding of how bitcoin works. She told me the order was canceled and that I should just re-order and pay with a different method i.e. paypal or cc. I told her that sounded good, except one thing. Bitcoin was sent, and I can't get it back.

She forwarded me to the "pay support" department where they found the transaction, noted it still needed a few more confirmations to issue a refund, and that they would email me with a request for a return bitcoin wallet address later today or tomorrow. About an hour later I received the email.

I shipped them my wallet address, and I received the USD equivalent (at current rates) in bitcoin right away. Thankfully it was within a few bucks of the original payment.

I am very satisfied with the outcome, but it did scare the hell out of me for several minutes.

Community Alert! Do not trust Overstock.com with crypto payments!

Last week, I bought a $20 polo shirt from their site with Bitcoin just to show my enthusiastic support that they accept crypto. This morning I received an email from them telling me my order has been successfully cancelled. I called their Loss Prevention line to tell them I didn't cancel my order. The customer service rep said they didn't receive my money (even though my wallet shows 416 confirmations). I also don't see my refund in my bitcoin wallet (even though they said they completed that refund back to me).
They put customer service rep "Page" on the phone with me. She said the staff there made a (verbally spoken?) mistake, whereby one staffer told another one that my payment was not received so they prompted the order cancellation on their end. But Page sees now that they did in fact receive my money. Wait; this gets worse.
They apparently don't correctly use the bitcoin payment protocol. That protocol provides them a return address to send a refund to a customer should they choose to conduct a refund. But instead, Page told me I can recover my money at Coinbase with my Coinbase account. I told her I didn't use Coinbase to buy anything and I don't even have a Coinbase account. She said I'll have to open a Coinbase account then so as to begin the process of recovering my bitcoin refund from Overstock.com.
I reminded this Overstock.com customer-facing representative that I did not cancel the order. I do not want to open a Coinbase account to get my Overstock refund due to a mistake introduced by Overstock staff. If saying I'm the victim is too harsh a word, okay, I am the inconvenienced customer that did my part of the transaction and that Overstock failed to see through on their part of the same transaction. I asked Page to take more ownership of the problem than to send the customer on a journey through Coinbase’s customer service channels which is notoriously bad. I told her to involve leadership at Overstock.com if necessary, and to show a good faith effort on their part to make this right. Not this dismissive reply for the customer to embark on an expedition through Coinbase for my precious crypto.
The customer service agent was curt, basically telling me in a monotone voice that Overstock.com will not take accountability for their mistake and ship me the shirt while chasing down the payment they erroneously sent away to Coinbase. Even when I warned her the harm to Overstock.com’s reputation this will cause when I tell my story to the crypto-currency communities, Page seems to believe the financial cost of a brand that can’t be trusted is not as expensive as eating the cost of just $20 dollars to send me the shirt she concedes I did pay for.
I reasserted to her my prerogative that I should not open a new account with another company that I don’t want to do business with to recover my money from a transaction mishap done by Overstock.com. She said she’ll try to get the money back from Coinbase themselves instead of putting this work on me. She said, and I quote, “It’s a 50/50 chance we’ll get that money back from Coinbase we sent them”. She said it may take a couple of business days before they have any news for me whether they could do it and, if successful, it may be over a week before I get either my money back or get that polo shirt I paid for.
What a pain in the ass! Hey, Overstock.com CEO Patrick M. Byrne, are you seeing this?!? Surely you care more than Page about your staff damaging your business’s brand reputation, right? Make this right. If you do, I’ll circle back here and let everyone in this community know that you stepped in and expedited quality customer care.

The demand from consumers is increasing as the benefits of digitally native payments are becoming more apparent. Crypto can save both customers and businesses money and time and can also increase the security of transactions.

Crypto payments may not be mainstream yet, but more and more businesses are responding to the growing trend and are now accepting crypto payments either directly or indirectly through a third party.

For example, online retailer Overstock accepts crypto payments directly from any customer, around the globe instantly.

Overstock: Benefits of Bitcoin Purchases
Overstock was one of the first major retailers to accept Bitcoin in 2014 and has continued to make a name for itself in the crypto space launching its own blockchain based capital markets solution, tZero. Others such as Microsoft, Dish, and Shopify have followed, accepting crypto payments in exchange for their goods and services.

For Customers...

Less Fees
Banks make a lot of money off of your money. They charge fees for a variety of services like credit cards, savings accounts, ATM deposits and withdrawals, and more.

Managing your funds in a crypto wallet versus a bank offers significant savings. In most cases, opening and holding a crypto wallet, unless one chooses to purchase a hardware crypto wallet or prepaid card, and using it for crypto payments is completely free. Of course, this largely means that maintaining custody and responsibility of your crypto (through keys, seeds, hardware, or otherwise) is almost entirely up to you.

Owned Data
Financial institutions and retailers collect and retain a wide range of customer’s personal and financial information. Your bank tracks anything from your name, address and social security number to your net worth, investments, account balances, and credit score. On the other side of the transaction, retailers are collecting your browsing and purchasing history as well as your basic personal information.

With crypto, the only data needed to process payments is two strings of numbers – the customer’s address and the recipient's address. Of course, crypto transactions aren't completely anonymous because most blockchains are public, and personal information like your name and address are often still collected by retailers. Despite this, crypto transactions collect and retain significantly less personal information than standard credit card transactions.

The fewer intermediaries involved in a transaction, the fewer opportunities there are for your data to be commercialized. Not to mention, by making transactions peer-to-peer, business yield more profit and are less pressured to gain revenue through sales of customer data.

Borderless Payments
Crypto assets are borderless by nature. Bitcoin, for example, isn’t owned by a centralized body or issued by a single country. It’s decentralized which means it’s also global. Crypto payments can instantly cross borders with minimal fees and without the need for an intermediary like a remittance business or a bank. All that’s needed to process an international payment is an internet connection and a device like a cell phone or laptop.

Removing the third party from the equation opens the doors for millions of people around the globe without access to banks (“the unbanked”), giving them access to the global economy. The opportunity for crypto payment adoption in places like Nigeria where an estimated 100 million people have access to the internet, mostly through mobile devices, but only 31 million hold bank accounts, is huge.

For Businesses...

No Charge Backs
The current electronic payment system forces businesses to take a substantial risk when processing payments. When you purchase something with a credit card, you’ll often see your transaction as pending on your statement. That’s because your payment isn’t actually as instant as it appears. It has to travel between a customer, two banks, then finally, to the merchant.

The lack of speed and the need for multiple parties gives customers the chance to take an item only to cancel their payment before it’s processed, leaving the business high and dry. With a crypto payments, it can't be reversed once it is processed. It’s instant and permanent, which means companies don’t have to worry about chargebacks.

Loyal Customers
CheapAir – an American online travel agency – has reportedly processed more than $5 million in Bitcoin payments since 2013. The CEO of CheapAir Jeff Klee told Forbes that he likes "customers who pay in crypto because they are loyal." He also noted that they’re more likely to “buy higher ticket items.”

Many crypto users are seeking out businesses that accept crypto and are likely to be loyal to those who do. Not to mention, studies predict crypto assets could be used as a mainstream means of payment in the next decade. Businesses that get ahead of the curve will likely reap the benefits of mass adoption.

While crypto payments have a long way to go both in terms of adoption and scalability, the benefits to both businesses and customers are significant enough to radically improve the way transactions are conducted globally.

Wtf is this bullshit Overstock??

Well wtf is this? I don't have coinbase and don't plan on signing up for it. I just paid $24 for a screwdriver set, and instantly after I sent the coins to the address, it gives me this message!...

Bitcoin Anonymity Question

Currently, while intrigued by the technology, I don't understand the ins-and-outs of Bitcoin, so this may be a dumb question.
Suppose my friend sends me Bitcoin by knowing my Bitcoin address. This transaction can be evidenced within the Blockchain. Now that my friend knows my Bitcoin address, can he then see how I spend my money forever going forward since all transactions are recorded on the Blockchain? I get that he may not know who I'm sending the money to, but he would know when I spend money and the amount. Is this right? Wrong?

Question about Coinbase's credit card payment method ToS

When you go into "Add Payment Method" and hover over the credit card ToS it says this:
Coinbase cannot make payments to you via this payment method, If you wish to sell bitcoin and withdraw funds, you will need to link and alternative payment method, such as a bank account that supports payouts.
What does this mean? All I want to do is buy Bitcoin and then use it for online purchases, possibly even transfer it to my own Wallet. Can I not do this if I've purchsed my bitcoin via Credit card?
