What is Bitcoin - Gyft

Pay for thousands of restaurants with Bitcoin Cash. Buy Uber gift cards with Gyft and pay with BCH. The Uber credit buys anything at Uber Eats.

Works great. Spreading it around at Uber Eats, Uber, whole foods, sbux, Nordstrom rack, delta airlines, lots more.

Buttcoiners learn that Gyft was purchased by large credit card processing company. Existential crisis ensues, as paying with credit card is cheaper than paying with bitcoin.

I bought from Overstock paying with bitcoin directly and using Gyft cards. Gyft is better, here's why.

First, Overstock uses Coinbase to process transactions, while Gyft uses Bitpay. Bitpay consistently offers a better rate for the buyer. In my case, Bitpay gave me $820/BTC when Coinbase gave me $805 at the exact same time.
On top of that, Gyft gives you 3% back as "gyft bucks".
On top of that, buying gyft cards allow you to lock in an exchange rate which is advantageous if you know you're going to buy an item in the future that's not incredibly time-sensitive. For example, I knew I wanted to buy something from Overstock for $200, sometime in the next few weeks. So I bought $100 worth of bitcoins, waited for the exchange rate to go in my favor, and bought $100 gyft card as soon as my $100 in BTC was worth slightly more than what I paid. Repeat (or break it down into smaller chunks for less risk). Granted this won't always work, especially if you happen to buy right before a "crash", but for the most part bitcoin varies (up and down) by $20-50 every day. As long as you're not greedy and keep your eye on the exchange rate, it's very easy to break even if not profit slightly, from buying gyft cards with BTC as soon as it becomes worth more/equal to what you paid. Even if you lose 3%, the points that Gyft gives you for paying with bitcoin make up the difference, assuming you use Gyft regularly. That being said, I've done this many times and have never lost out, the worst that's happened is I have to wait longer than expected.
EDIT: another reason gyft is a great company that embraces bitcoin.

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".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

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
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

1 When paying via PayPal, I can only send payments via Goods and Services, thus you will be charged a fee. If you'd rather not face this fee there are plenty of alternatives. 2 Skrill charges an upload fee and transaction fee, both of which will be taken from the payment. 3 Larger denominated gift cards preferred. 4 PayPal is the only payment option. 5 I can't send less than $10 in crypto per Coinbase's rules.

What I don’t buy:

  • iTunes from anywhere but the US
  • Google Play from anywhere but the US
  • Hilton Honors
  • Spotify
  • Steam
  • old navy/gap/banana republic
  • Hot Topic
  • PSN Canada or UK
  • Xbox Canada or UK
  • Xbox live gold
I will buy gift cards in almost any denomination, although if you are offering an item worth $100 or more we will need mod approval. I will not trade Bitcoin for cash, or do any other cash for cash trade, as that would violate rule 6, and I don't sell gift cards. This is a buying post, not a selling one. Any fees are built into the price.
Here are my GCX Rep profiles with 943 trades worth more than $61,000:
Important: before you send your codes please make sure your account is secure (if your password is twelve characters or less it's best to assume your account has already been compromised; your password should be eight randomly selected words, see 1 and 2). Scams where compromised accounts are used to leverage reputation to scam an unsuspecting user, used to steal codes during the middle of the trade, and steal unused gift cards the victim was saving for later are increasingly commonplace. If you have any concerns as to your account's security, please reset your password now and force logout of all sessions. Thanks

/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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

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
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or 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
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
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.

How I live on BCH, and why more people should.

TL;DR at bottom

I think we need to seriously examine our path forward to growing the community. I believe we should focus less on getting businesses to accept BCH and focus more on living on BCH, and getting other people to become full time users. I've been moving towards living on BCH for some time now. Let me go over the benefits to the community, the benefits to the user, and the methods for accomplishing this.

Firstly, without a strong user-base, companies accepting BCH will do us no good. Sure, YOU can spend it more places, but that business will not get much more traffic because of accepting the coin. They are likely to drop the practice once they've lost interest. Imagine invading a country. Do you start by invading the capital? No. Do you start by invading the edges? Even still, no, you start by building an army. We need an army of users if we want to hold any ground we take. To be clear, what I am saying is that if we want businesses to continue accepting BCH, we need a strong, large userbase.

Next I will go over the methods I use for living on BCH and their benefit. I primarily use 3rd party services such as gyft or even the Shift card (https://www.shiftpayments.com/card). Only a couple of the people I do business with accept it directly, but that's fine and it still does the BCH cause good.

Get your coins:
The way I get my coins is simple, and I imagine most people may do it this way in the USA. I have a recurring buy in my Coinbase account on the same day as I get paid my USD. This amount is the same amount as all bills and other expenses I pay in BCH, plus about $200 a month for recreational activities or purchases. This comes out to about $500 every two weeks.


I know some people think there's no point in using BCH if the receiver converts it straight to fiat or some other coin, but I think this is a wrong assumption. I've covered this a bit and I cover it more below.
Why I use the Shift Card:
There are advantages to the BCHer who uses the shift card. Firstly, using the shift card (which is a debit card that can link to any coinbase asset you have) allows you to segment your money. If you don't have a credit card, this protects the money in your bank account while only putting your coinbase funds at risk of fraud if someone steals your card information. I keep the funds in my coinbase account low in order to combat this threat. Next, holding value in crypto rather than dollars resists entities from stealing from you via inflation. Third, holding crypto in any way at any time increases demand ever so slightly. One convenient thing about the Shift card is you can just send money from your own wallet to coinbase whenever you know you are going to go make a purchase. Best to do this ahead of time.

Why I use Gyft:
There are advantages to the BCHer who uses Gyft. Gyft is a company (who has a convenient mobile app) that sells gift cards for various retailers. Check out their website to see where all you'll be able to spend BCH via Gyft. The advantages include directly holding your coins with your own keys and just completing a BitPay invoice when you want to buy something. This method has all the advantages of the shift card plus holding your own keys and subverting the VISA system, thus avoiding a degree of surveillance.

I believe if enough people used BCH wherever they could, the demand for the coin would be higher, and

TL;DR:
I use the Shift card and the Gyft app, along with a couple other things, to try to live on BCH.
PS: If you do this, be sure you have an emergency fund big enough to cover any market crashes so that you can still, you know, eat.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.

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
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Proof of Failure - "I'll get you next time Salty Roger" :-)

"actus non facit reum nisi mens sit rea"
Just under 7 days ago I posted the following SHA256 hash to both the BSV blockchain and BAB blockchain.
I actually posted at 2019-06-16 20:00:00 but it took some minutes (as you'll see I predicted) to appear in the next block of the aforementioned blockchains, thus remaining a permanent immutable record.
memo.sv post Block Time: 2019-06-16 20:38:22 Block Number: 587160
memo.cash post Block Time: 2019-06-16 20:29:44 Block Number: 587318
This is verifiable proof that I held the plaintext to make this hash on that date. The hash as you can see is which is a SHA256:-
52f42a5a4c073a2a14ed76e5a1d356c4586e6f2dea2a91d9a3dcf5f57799442e
Just after posting to the blockchain this hash, I sent private messages to 3 members of this subreddit with the following text, and thus this is the reason why I am now forced to reveal the hash, as I expect them to take my words seriously.
It doesn't matter in the grand scheme of things (as all I did is cryptographically proven) that I did this, however I wanted to so I would be forced to reveal the plaintext within 7 days. I won't name them, but if they want to confirm that they did indeed receive this message then I'll leave that up to them.
Hi guys. Look I am doing something kinda funny here, but for now needs to be secret. Here is a SHA256 hash, write it down!
"52f42a5a4c073a2a14ed76e5a1d356c4586e6f2dea2a91d9a3dcf5f57799442e"
If I don't reveal what plaintext is the source of this hash within the next 7 days then it means I am a fraud, and I am not to be trusted and I request I am permabanned from the subreddit, and all communications with me should cease.
This hash has been published on both the BSV & BAB blockchains as a memo message, as proof it wasn't created after the time it appears in the blockchains, and proof of immutability of content.
You can see it here (BSV):- https://memo.sv/profile/1gr5whAEV4ffA6df71JTdQ7gSNQWTkgnm Or here (BAB):- https://memo.cash/profile/1gr5whAEV4ffA6df71JTdQ7gSNQWTkgnm
And timestamp will be a few seconds or minutes after timestamp below, as and when message gets confirmed in next block on each respective chain. PoW!
If I happen to be banned from reddit in the meantime don't worry as hash reveal will take place on these memo channels within 7 days.
If this works you're all gonna LOL real hard cause it will cause one big massive social media shitstorm! And we all know the only way to destroy a PoSM shitcoin like BAB is with social media!
Cheers fellas! jim-btc 2019-06-16T20:00:00Z End of message.
I actually sent it to them as an image
This is all those 3 members have seen, and all 3 have confirmed, one with "I'll be watching" another with a "LOL" type response and another with a rather concerned "what's this?" type response. I gave them no further information - so now all reading this post know exactly the same about this all as they do - which is basically nothing, other than this hash 52f42a5a4c073a2a14ed76e5a1d356c4586e6f2dea2a91d9a3dcf5f57799442e must be something interesting.
So what was the plaintext behind this hash? What does it have to do with Salty Roger?
Well I'm gonna take some inspiration from Dr. Craig S. Wright here to add some tension... I still have a few hours to reveal the plain-text, which is in fact a computer program. We shall all see.
UPDATE
OK here it is: https://gofile.io/?c=FsGtJD
Go check that SHA256 hash.
Here's the code:
#!/usbin/env python # bab-destroy.py # Should work in Python2.7 & Python 3.x # Author: jim-btc # If you change any character in this code (including newlines so careful # Windows users - it will fail to reproduce the excercise! # This is BAB Destroy. Some code designed to make Salty Roger Ver, head of # Bitcoin Cash (BAB) look very stupid and get owned by cryptohashes once again. # # The BABies (that's users of said coin) seem to spout the mantra "Code is Law" # so I thought what better way to own them all than by using some code to do # it! # Purpose of this program is to generate a fake (unspendable) Bitcoin address # and to hash various messages. Hash for this program (hence the entire process # in the pwnage of Salty Roger will be published on both the Bitcoin Cash (BAB) # and Bitcoin (BSV) blockchains as "proof-of-LOL" so what I am doing here can # easily be verified as non-illegal and non-fraudulent *after the event* by # simply running this code and verifying all messages/hashes produced - to # replay the sequence of events as it were. # # A non-spendable address is used to demonstrate even if Roger was dumb enough # to send BTC that it is the equivalent of burning money - i.e. nobody can # benefit. Also for any legal eagles reading allow me introduce some Latin: # "actus non facit reum nisi mens sit rea". Interesting case study to be made # perhaps regarding blockchains as immutable evidence. # The idea is the following happens:- # # 1) Hash of this program code is published on BAB & BSV blockchains to proove # timestamp that this effort was started, using memo.cash / memo.sv # # 2) A few community memebers from Bitcoin (BSV) subreddit are sent a hashed # message stating that there is a hash on BAB/BSV blockchain and if I don't # reveal how to make it within 7 days then I am a fraud, a scammer and should # be removed from the community - this is to ensure nobody can claim the # argument "jim-btc was just testing to see if Roger would pay" and to # ensure revealing of this code regardless of the outcome. # # 3) Roger recieves a message from me basically stating "Pay me 1BTC and I will # stop attacking your coin and community and work for you attacking BSV". # # 4) Roger publishes this message on /btc (or /npc as it's better called) # and tries to state that jim-btc is a scammer, and possibly that this is # a scam/community atack by the entire community of BSV. The idea is that # Roger basically publisizes this for maximum effect so when the truth is # revealed his own publicity owns him. An alternative (but very unlikely) is # that Roger sends 1BTC to the address - where I then publish this entire # message chain to prove (once again) that Roger is an idiot and has no # problem employing sockpuppets for nefarious purposes and has just burned 1BTC # for his very silly efforts! Remember if he sends any funds there - I cannot # spend it as you see that the public address has no corresponding private key. # (it's a fake address). # # 5) Bonus LOLpoints will be rewarded if this news makes it to Roger's Twitter # account and/or his news.bitcoin.com website as some sort of proof that # "criminal blackmailers are attempting to destroy BAB" or the now famous # classic quote they use "It's an attack" as they keep needing to invent a # common external enemy like Orwell's 1984 as some way for cohesion in their # destroyed and rotten "community". It is expected that as Salty Roger loves to # play victim he shall play victim to maximum effect. Let's hope so! # # 6) Program code is revealed. Orignal hash on BAB/BSV blockchains is shown as # matching the hash of the program code. Roger looks dumb, all BABies are # awakened as to just how easy it is to attack a PoSM (Proof of Social Media) # shitcoin such as Bitcoin Cash (BAB). The crypto world laughs, lawyers debate # the legality of this all - everyone is confused but most agree Roger has once # again proved he knows nothing about crypto and is easily spoofed. # # People read this program code and these comments and find out just how bad # things are with BABcoin. They sell the idea of "decentralized development" # when in reality Amaury Sachet (ABC node developer) bans Andrew Stone, LEAD # developer of Bitcoin Unlimited from any meetings. It also encourages BABies # to look at the ideas floating around in the dev community - such as spending # funding money on developer get-togethers when clearly the fundraising they # are doing is supposed to be paying for developers to develop. People are # encouraged to look into the transparency of all fundraising and realise that # this is not a sustainable model for a anti-business coin such as BAB. # # Once again I'd ask people to seriously debate the difference and the # narrative:- # # "Satosh added checkpoints to Bitcoins source code - checkpoints are OK" # -- the BAB narrative # # The reality:- # These checkpoints were added days/weeks/months after the blocks were mined # for pretty obvious reasons. # Amaury Sachet (shitlord dictator of ABC) added them within ~10 minutes of # blocks being mined and colluded with exchanges to use this special software # within minutes. That is not fair competition, this is not PoW. That is a PoSM # shitcoin and shall be destroyed - only way to do it is with social media! # # This program is dedicated to unwriter and Craig S. Wright (Satoshi Nakamoto). # # Read unwriters phenomenal message to all devs:- # # https://medium.com/@_unwritethe-resolution-of-the-bitcoin # -cash-experiment-52b86d8cd187 # # OK - let's get started... # # These are the only 3 functions we need to import. from binascii import hexlify from hashlib import sha256 from os import path BASE_58_ALPHABET = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz' # First let's make a public key based on some text, unless we manage to break # cryptography we will have no way of knowing the private key for this message # thus any coins sent here are effectivley burned (unspendable). # This message will give us fake address 1MCpARZExPsW5EmBMEYj2NoyUxaoWyZt8N BITCOIN_PUBKEY_MESSAGE = b'Roger Ver is an idiot, jim-btc owns him!'
