I have kind of missed this split. Do I understand it right that I cant get BCC for bitcoins that I have on localbitcoins and paxful?

I understand that's right, you need your BTC to have been in your own wallet (with private keys) at the time of the split.

It seems like you cant sell them now anyway. Looks like the exchanges are selling their own hoard while blocking deposits.


In an industry that thrives on greed, these kind of practices shouldn't surprise anyone. However, at this point there aren't enough blocks coming through to safely allow user deposits. In this case we should grant exchanges some slack. By the time deposits are allowed, people will end up selling their BCC's at 0.05 BTC (if it doesn't turn out to tank even deeper).

There is a lot of fear about importing private keys. And yes that is very risky but if you're sending all your coins to a new wallet then you have new private key. You're importing the old keys into the BCC wallet with 0 bitcoin on. When the fork took place, the bitcoin you had in that address/that old key, had bitcoin on and that is why the forked BCC will have the equivalent amount inside. But yes I wouldn't go downloading some random unproven software. It seems like you cant sell them now anyway. Looks like the exchanges are selling their own hoard while blocking deposits.

In the fray since 2013.

Hello everybody.

I have some BTC in a core Wallet and some in an Electrum wallet.

Step 1: Transfer all BTC to a third wallet. Never use previous 2 wallets again.

Step 2: Claim BCC.

Now the questions:

1. In order to avoid installing untested software couldn't I extract my private keys (from both wallets) and then import them on a single online wallet, like the one offered by BTC.com?

2. is it a problem if the wallet no3 (my new BTC wallet) had exchanges with previous 2 wallets

you can NEVER be too paranoid with your private keys
Well partially true, but if it's enough/over your 'risk taking level' it's fine

Some 15 years ago, i've lost (then) very important information which i have 'resurrected' form my 6-th backup (floppy disks where at that time very insecure and failing all the time).
Now the risk is not that your floppy disk gets damaged, but your HDD/OS gets compromised - both risks and solutions have changed and they will in the future, but the 'right choice' is always the same - more backups than you can afford to loose / more protection than someone can afford to brake

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

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.

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.

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

I got BTC-e'd... I got WEXed...
August 02, 2017, 12:36:33 PM
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?




Your Electron cash client is probably synced to the BTC chain instead of the BCC chain. Your BCC have probably not moved.
I can't send BCH anywhere because the wallet shows "not enough funds". How to force Electron Cash to sync to the right chain?

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)

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.

You can see that on the following website:https://github.com/bitcoin/bitcoin
Wrong. This repository has nothing to do with BCH.

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?
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?
