Make sure to see this topic by theymos also: https://bitcointalk.org/index.php?topic=2059111.0

Note: I do not condone this behavior but it is happening and many consider it as "free money" or "airdrop" so i've made this to help prevent loss and possibly help those who want to sell as fast as possible to get the best price as it goes down.

On August 1st, a small group of people are planning to implement a non-compatible upgrade to the network, raising the blocksize limit to 8MB and removing SegWit. As this upgrade does not have a wide backing of the network, this "hard fork" would split the Bitcoin network in two. After this split whatever amount you have in bitcoin you will have the same amount in their chain known as Bitcoin Cash (BCC for short).
These are the ways you can claim it and be the safest possible:

According to this [1] and [2] BCC has a two way replay protection. This means if implemented correctly and honored by miners any transactions made in BCC chain should be invalid on bitcoin chain and vice versa. This makes things a lot easier.

Ways to claim your BCC:

Method 1, using an exchange before August 1:
Risky, for the Lazy, Easy
Some exchanges have promised to credit their users their BCC tokens in case the split on August first happened. this means if you have any balance in your account there you will automatically receive the same amount in BCC.
Risks:
1. Your account can get hacked, the exchange may get hacked, the exchange can run away.
2. You don't control the private keys so you are trusting the third party to do it for you. and they may mess up and lose the tokens.
3. It may take a while before they credit your BCC tokens, or add a market for you to be able to sell them, or let you withdraw them to sell elsewhere and every second counts in case you want to act fast to get the highest price.

Benefits:
1. It is easy and suitable for the lazy.
2. If the exchange has the market already or adds it fast on August 1, you can be the fastest to sell without missing a second. So you will get the best price before it crashes.

Important
Read the risks and understand them before you decide on doing this.
your time is running out, some exchanges will close their deposits on 31st. Make sure it is not yet closed, you don't want your coins in limbo!


Method 2, using a BCC client After August 1:
Harder, Safer
This method requires you to do everything, this means separating your coins yourself and then spending them. It is not hard, but it takes some time to do it. You also are taking the risk of using a new untested code given to you by people we don't know and have no track record to check.

Risks:
The BCC clients are new and unknown, and we do not know who is releasing them (do not confuse the similar names such as "electrum-cash" with the original client "electrum" they are different[3]). They are rushed and nearly untested. They may have bugs or worse. Extra care should be taken (explained in summary below)
The replay protection may not work (Don't think this is true, just a cautious assumption IMO) (explained in summary below).

Benefits:
You control everything!

How To:
Summary: My approach is to separate the coins first and then spend them, this way you don't have to worry about replay protection or the wallets you download (because it is a new wallet created by a small group of people we don't know or trust and it is rushed and untested).
This is all After August 1 and the split.

1. First split your coins by spending them on bitcoin's network. Simply get a new key and send all your funds to it with the wallet client that you already have and is running on the main network.
Extremely Important
If you are using a deterministic wallet (ex electrum with seed) you must create a new wallet with new seed not just a new address from the same seed. (edit: Read about Electrum WARNING (https://bitcointalk.org/index.php?topic=2056996.0))

2. Download a BCC client to import your old keys (which are now empty of bitcoin but still have BCC) and use them as you wish.
I am aware of 2 clients (download at your own risk):
- Bitcoin ABC: You can download it from "releases", compile the repo or download binaries from their website.
This is a full node.
Link: https://github.com/Bitcoin-ABC/bitcoin-abc
- Electrum Cash (This is a changed/edited version of Electrum by other people than Electrum team [3])
This is a light wallet (SPV)
Link: http://www.electrumcash.org/ (update 2019: link is changed to https://electroncash.org/ and https://github.com/Electron-Cash/Electron-Cash/)

Important
It is best if you do all this offline and on a separate computer and preferably on a live linux with no persistence and no access to any of your hard disks.
Suggestion: Ubuntu[4], Tails[5]
- Burn them on a DVD or make a Live USB [6][7]
- Disconnect internet (if you do it, you need to make a raw unsigned transaction online and transfer it to offline system to sign)
- Boot up into that Linux
- install BCC client and import your private keys (or seed if it is electrum-cash)
- spend.

If you found any mistakes or lack of explanation help me fix them.

Happy Dumping

Other website which will give BCH for free are:

- kraken
- cex.io
- freebitco.in
- bitfinex

I agree using these websites is quite risky though...

I think the risk for average person is too big to even consider this. I mean, you can earn $1 and you can lost $100 or even $1000 in same time.
Be very carefull what you are doing.

So if I store my Bitcoin on exchanges which are in supported status I will give free amount of Bitcoin Cash equivalent to amount of BTC that I store on it?

if the exchanges clearly said they will credit your account with BCC equal to your bitcoin then yes you will get BCC after the fork if they don't mess things up.

Personally, I don't like to store my Bitcoin such of exchange site. Continuously getting message various platforms they won't support the new blockchain or coin on that date. As long I came to know, their only chance to get the BCC equivalent amount of BTC, if you have full control over the wallet.

Thanks, this is very helpful.

A very helpful guide. Many are lost at the moment as there is more and more technical information coming out about Aug 1st than they can handle.

*they will  credit you half of bitcoin and half BCC ?
*they will have same price or convergent price ?

example:
an exchange like bittrex promises to credit you BCC 1:1 for the balance that you have by the time of BCC hard fork.
if you have 1.4238 bitcoin in your balance that won't change. you will still have 1.4238 bitcoin after it.
also they will open a new field in your wallet and call it bitcoin cash (BCC or BCH or...) and give you 1.4238 BCC in it.

as far as price goes, we have to wait and see what happens. it is not easy to predict.
you can see bitcoin price change here: https://bitcoinwisdom.com/markets/bitstamp/btcusd
you can also see BCC price change here: https://coinmarketcap.com/currencies/bitcoin-cash/#charts

Beware of scams.

Bitcoincash will be the paradise for scammers, fake websites with BCH wallets, etc... all scammers want only one thing: your keys = your money.

There are no (!!!) Tested wallets for BCH.

Exchanges that support BCH might be the safest harbour or you wait until the BCH wallets have been tested.

is it possible to just c/p the "blocks" folder to abc directory? so i dont have to download the complete chain?

Good read, thanks.

I hold several altcoins on several exchanges. Say I sell my altcoins AFTER the split and then transfer the BTC received to a Bitcoin cash supported wallet... Will I then receive my equal share of Bitcoin cash?

NO. you'll receive equal amount of bitcoin cash for any amount of bitcoin that you have BEFORE the fork.

Thank you so much for all the details, it was actually needed as most of the new investors will not be thinking it in the secure way.
What do you think of mycelium wallet.? And holding BCC for long term.?

i've never tried Mycelium so i can't say anything about it. check out its dedicated board and ask your questions there: https://bitcointalk.org/index.php?board=231.0

as for holding, it is a speculation question. it is hard to answer. in short term BCC price will surely drop hard. and depending on "how hard" it may or may not be able to recover. we still don't know how much money they are willing to throw at it. the miners dedicating hashrate will surely lose a lot of money for a considerable amount of time. and a lot of other things to consider before saying anything about its future.
one thing is for sure, nobody is happy about it and it has so little support. and i will personally hold less than 5% of my reward because i have some plans for it (for testing some stuff)

Ok. Thank you for the explanation. I was thinking about November and BCC may get valuable at that point. Still not decided to hold or sell but seeing the support, it feels like selling them now is the better option.

Good read. Thanks for your post. I will try and install the wallet and import my electrum seed, but only then when I have read comfirmations. Still feeling unsure of just give some client my seed/ keys. Even IF I am offline.

Nice guide and a handy list of exchanges, for anyone thinking of using an exchange now I think pretty much all of them will have frozen deposits as we are quite close.

So after the fork means ;

What time should spend BTC or out from the previous wallet? After 30 minutes or 1 hour or next few minutes??

Nice guide i added to bookmark in case if every body are converting into bitcoin cash this guide will help but hoping this guide will be change once there is a new step by step can clam bitcoin cash easily..
For now i still thinking if bitcoin cash will be useful in the future.. since many people are still choosing to use and stay only for bitcoin.. but lets see after august 1 sooner august 1 will start.. and hope we will see a good changes soon. .

Ok just to make sure i got this right. You downlaod BCC wallet on a separate computer , You Then export your BTC core private key from pc 1 and you then copy your BTC core private key into PC2 running the BCC wallet ???

in other words you use your BTC core private key and paste it into the BCC core ??  that way you will have both coins in different wallets ?

Good guid! But i am new and don't know many things.So I store my Bitcoin on exchanges which are in supported status.

good question, an i am not sure about the answer!
you see the problem with bitcoin cash hard fork is that they are not setting a block for their fork for example saying we will fork after block 478500. instead there is a time which is Tue 1 Aug 2017 12:20:00 UTC. and it may take a while before they find the first block because of low hashrate. possibly 1 hour to 1 day.


you should first spend your bitcoin *After* the fork and *before* importing it in the BCC wallet.
it is not pasting, it is called importing. the rest look correct to me.

anyone that made a guide for this  maybe with pictures? detailed guide i mean...

i want to sell them and not sure how to do that :)

Thanks for the guide. It's very helpful. I have a Blog in Brazilian Portuguese language. Can I translate it into Brazilian Portuguese?

recommendations to install electron cash on another computer?

Hey Pooya,

Not sure I quite get what you mean by "spending it". After the fork, which as you say we should wait at least a day for to be safe, we should spend our btc, then transfer our private key to computer 2 where we have our bitcoin cash wallet and then import our key?

By spend do you mean transfer our btc to another new wallet with a new seed?

Here's what I understand:

1. Create new BTC wallet with new seed (before or after the split or it doesnt matter?)
2. Transfer BTC to this wallet (before or after the split?)
3. Export private key of this new wallet.
4. Install BCC wallet on another computer
5. Copy private key to this computer and disconnect it from the internet
6. Import private key to BCC wallet

Part of this guide was translate to brazilian portuguese, here:

Thank you!

Hi,i use electrum wallet,now can i transfer my BTC to new electrum wallet or not?how long should i wait until i can transfer my BTC to new electrum wallet?i want to get my BCC as soon as possible.

yes, it is best to install any bitcoin cash wallet on a separate computer to protect your main computer from it. and as i said if you don't have another machine just use a live linux with minimal access to your system and no persistence.

yes that is what i mean by spend: sending bitcoin from "old wallet" to "new wallet" on bitcoin blockchain then moving the old wallet (seed or private keys) that are now empty to computer #2


1. for creating it doesn't matter (besides we are already after the fork)
2. transfer must be after the fork (now is good)
3. no, your new wallet is created to protect your funds (your bitcoins) you should not export private keys of this wallet anywhere. what you export is the OLD private keys which are now empty of "bitcoin" but still has the "bitcoin cash" on it.
4,5,6. correct as long as you are doing it with OLD wallet's private key.


well done.


make sure to create a new wallet and you can transfer your BTC to a new electrum wallet now. wait for about 30 confirmation.
then install electron cash on another computer and import the old seed there

Hi I followed this tutorial:

1. Install Electron Cash on a machine that does not have your
 Electrum wallets.

 2. Wait until the BCC hard fork has taken place, and a few BCH blocks
 have been mined.

 3. Move all your Electrum funds to a new Electrum wallet. This will
 move only your BTC, and not your BCH, because the BCH blockchain has
 replay protection. Wait until the transaction is confirmed.

 4. Enter the seed of your (now empty) old wallet or private keys in
 Electron Cash. Since the BTC have been moved to a new wallet,
 entering your old seed in Electron Cash will not put your BTC funds
 at risk.


On Electron Cash I disabled Auto Server and chose casharia but I get only my BTC transactions and 0 BCH:

http://i64.tinypic.com/vdo85x.png

Where are my hidden BCH ?

has the problem solved?
same here....

Can someone reply to me please.  Did I do something wrong? Or should I just wait few days?

Why is Electron Cash not sending neither importing keys for me?

I tried importing a private key sweep, but it shows it still shows it's unconfirmed after 8 hours on the blockchain.

Then when I tried to send my confirmed BCC balance, which I imported before Augest1,  I get:

error: The transaction was rejected by network rules. (16: mandatory-script-verify-flag-failed (Signature must use SIGHASH_FORKID))

[010000000002b5......

Why is it not confirming my imported key? and why is it not sending my confirmed BCC? Any help appreciated thanks

Does Electrum send both BTC and BCC if I sent BTC to another wallet with it after Aug 1?



I changed to follow a BCC server from the network settings.   I still get the same error message and cannot broadcast send my confirmed BCC,   and I still get unconfirmed imported key balance.

The question that I have:

1.  Has anyone verified if this electron cash wallet is reliable?

2. If yes, has anyone managed to get BCC (BCH) from original Electrum wallet seed method?

3. If not, Are there any other wallet reliable that doesn't have to download 120 Gb to get BCC (BCH)?

If I do not get the answers to these questions, I will not even touch the BCCs (BCH's) that have been generated until I get these answers.

 

what about exchanges? bittrex?

https://support.bittrex.com/hc/en-us/articles/115000808991-Statement-on-Bitcoin-Cash-BCC

And Exodus just released an easier way to claim BCH from your wallet on their last update release of their wallet:
https://steemit.com/bitcoin/@itsshowtime007/claim-bch-with-your-exodus-wallet

All clean and straight forward without needing to do anything with private keys or anything like that.
Just straight from the GUI interface. 8)

How simple can that be!? ;)
