First learn how Bitcoin actually works.

In the thin client section 4 you mention importing your "private keys". If i only had one wallet and only intended to send it to one wallet would your "private keys" read just "private key" . I've only got one wallet and only intend to send it to one wallet (very small amount)

What is a wallet? A wallet is a collection of key pairs. If you have BTC on multiple addresses, then we are talking about multiple private keys. If all your Bitcoin are on a single address, then you only need the private key of that address.

i would really prefer to use core because i only have to trust core, im in the process of installing it...

You don't have to trust Bitcoin Core. You can review the whole code yourself, compile and build the wallet. Alternatively, you are not just "trusting" Core, but every single person that has ever reviewed that code.

Thanks! I appreciate your help!

You're welcome.

learn how bitcoin works, lol, I gota' learn how to ask a question first.... i missed a sentence or two and really should adopt "import" and "export" more, it would show my questions in a different light...you must sit there shakin' your head half the night lol....

A paper wallet is the same thing as a normal wallet, the idea is to generate it offline (computer not connected to the web, preferably using a bootable CD) and to only use the private key when you want to empty it. If you decide to import the private key instead of sweeping it, you can then use it as any other wallet. I didn't understand your quesiton about a broker though, do you have the private key of the current address where your BTC are ?

I don't understand someone can claim BCH from his/her BTC without losing his same number of bitcoins ?
is this free money created ?

[AnfisKatechkin]

I sent a few bitcoins through blockchain.info from different addresses and after that I checked my balance of BCH via Electron Cash and what I saw: All BCH are sent at the same time with the same tx but blockchain like blockdozer or blockchair doesn't show this tx and balances of my BCH wallets is zero!  WTH? At this time I sent a few btc through Mycelium and it worked fine! Whose fault is it?

[Jafri101]

I think Bitcoin Cash will be just like an altcoin which can be bought and sold using Bitcoins. Though it is also true that some exchanges said their users will be deposited bitcoin cash in exchange of bitcoins in their wallets. And also there are some exchanges also that claims bitcoins will remain bitcoins.

[Ruderalis]

I see a lot of people cursing the bitcoin cash fork, but I only see profits, the bitcoin price still the same while u have receive a new coin with a value that a few hours ago rise until almost 700 $, so... I cant believe that most of people here are recommending to not claim yours BCC... Otherwise I feel to many people that not support bitcoin cash at it's beginning, like Coinbase and anothers exchanges, but had Bitcoin, are making huge benefits nowadays... so... reading this post looks like reversed world...

what is the risk to import the core private keys to this wallet? With this is not possible to control the same private keys to both chains?
is not better?

Never import private keys into a wallet. Import your addresses using the 'importaddress' RPC call and sign your transactions offline using 'signrawtransaction'. This way your private keys never touch an online machine, so there's no risk of a misbehaving program stealing anything. The MMGen wallet manages your keys and performs all of these operations for you automatically. MMGen now supports BCH. You can even run BTC and BCH nodes at the same time and transact simultaneously on both chains.

so can anyone explain what changed in BTC code? 

You can see that on the following website:https://github.com/bitcoin/bitcoin

Wrong. This repository has nothing to do with BCH.

Problems:
1) Malicious code.
2) Weak replay protection.
In either case, if you use the same private keys on BTC and BCH, you may end up losing funds. Why risk when you can prevent something like that from occurring?

Your Electron cash client is probably synced to the BTC chain instead of the BCC chain. Your BCC have probably not moved.

Thanks for the rundown.

Will be interesting now to see how miners get on board. At the time being, seems they can't mine a single block.

so can anyone explain what changed in BTC code?  

Quite a lot. Apparently they based their code on Bitcoin Core 0.14.x but stripped out Segwit. However, they intentionally obfuscated the changes and if you compare the repositories you are going to see a lot of changed code. This makes it very hard to review what they did, thus I wouldn't trust their wallet(s).

They reformatted everything for an 80-column screen, which makes little sense to me as no one programs on an 80-column terminal anymore.

That being said, it is possible to review key parts of the code. I've examined the sighash function, which works as claimed so I no longer have any doubts about the replay protection. The spec is in doc/abc/replay-protected-sighash.md and the relevant function is SignatureHash() in the file script/interpreter.cpp. It's useful to compare with the same file in the Core repository to see what changes were made.

How to review the Bitcoin ABC code:

    git clone https://github.com/Bitcoin-ABC/bitcoin-abc
    cd bitcoin-abc
    git diff --word-diff=color 964a185
    
(Commit 964a185 was the last commit before the ABC repository was forked from Core)

I can't send BCH anywhere because the wallet shows "not enough funds". How to force Electron Cash to sync to the right chain?

[sudip76]

 Thanks for update. 

[BitcSeo]

so again for the third time, why i should wait 30 confirmations and not 6 as opposite to 3 which carry some risk like theymos said?

More confirmations = more safety. The BCH chain will be susceptible to *easy* 51% attacks when the difficulty drops.

☞More confirmation, more safety will create more complication as well because trader's/buyer's will have to wait. right?


Thanks

how to claim BCH from electrum wallet ?

[OmegaStarScream]

how to claim BCH from electrum wallet ?

If you are speaking about Electrum.org then you can't really start using them from there, you need to install a BCH wallet like ElectrumCash (I'm not sure how clean or safe is it). Send the funds from your Electrum to another wallet, use your old seed of Electrum inside EC and the BCH should appear and you can send or receive them afterwards. Again, you must send your funds elsewhere before using your Seed into that new wallet, that ensure that your BTC are safe in case EC have a malicious code.

any idea how to split some coins i have to greenaddress wallet? Unfortunately i have enable there and multisig authy. I dont think is possible to do it.

[newguy05]

Thank you theymos and everyone else who provided explanation of this rather confusing process to get bitcoin cash coins.

Below is my simplified understanding and also a question based on all the posts i read, please correct if any is wrong:

1) Install a completely new and different bitcoin wallet client (ie if you have bitcoin core wallet now, install something like bitcoin knots wallet).

1)Send your bitcoins from your existing wallet client to the new bitcoin wallet client - this is done so if the existing wallet private key is exposed later to scammers you dont risk losing the bitcoins, since they have already been sent to a different wallet.

2) Get the private key from your old (now empty of bitcoin) wallet.

3) Install a bitcoin cash wallet client

4) Load the bitcoin cash wallet client with the now empty bitcoin wallet private key, and you should see your bitcoin cash coins.

5) Then you can use the bitcoin cash wallet to send the bitcoin cash coins as you desire.

My question is on the bitcoin cash wallet client - many of the bitcoin cash wallet states they are bitcoin wallets? How do i know the wallet i installed is a bitcoin cash wallet or bitcoin wallet, and related, the coins that appear after loading the private key, is bitcoin or bitcoin cash?

Basically how do you differentiate between a bitcoin cash wallet vs a bitcoin wallet? Almost all the wallet recommended on bitcoincash.org describes themselves as bitcoin wallets, NOT bitcoin cash wallets.  So how do you what coin you actually have after installing and loading the private key?

Also what do you guys recommend as the best bitcoin cash wallet and bitcoin cash exchange to buy/sell bitcoin cash, since coinbase doesnt support it.

[KNK]

My question is on the bitcoin cash wallet client

That's the sole problem. Right now there are very few BCH wallets and none of them is approved with the time so you risk installing a malicious wallet/software, which MAY steal all your funds both BTC and BCH and even some more user/password details available for your mac/windows/linux user account

So far there is no such known software, but it's YOU and only YOU who may decide to risk own funds

EDIT: I am very paranoid in such cases and may/(for sure) overreact, but ... 'better safe than sorry'

you can NEVER be too paranoid with your private keys
