If bitcoin forks, then how do you split your coins?
If you have the private keys in your control, you would need to import the keys into a wallet that's designed to split coins.
What wallet is that? I haven't heard of one. By the way, I use a mobile wallet. Like a lot of bitcoin users (probably most, actually) I don't sync the Bitcoin blockchain(s!) on my computer.
Otherwise, you would have to find an exchange that splits keys.
What worries me is this scenario:
1. I store my coins locally, with control of my own private keys.
2. The chain forks.
3. I can't find a wallet that splits coins.
4. I find an exchange that splits coins, but it turns out that you had to have your coins on the exchange
before the fork; they can't or won't split coins sent to them after the fork, even if the coins are older than the fork, for technical reasons or otherwise.
I see no discussion of these challenges. Have you considered the problem?
There will be no split anymore dude, segwit is going in, that's all, no more BIP148, no more UASF, no more bullshit, just segwit and 1 coin.
Now, if Jihan and Roger really decide to fork bitcoin into BCC (Bitcoin ABC/Bitcoin Cash which is the same as far as I know) then by august 1st, keep your coins in your wallet, and if you have 1 BTC you will recieve 1 BCC. To get that 1 BCC, im not sure how it works, you load the same wallet.dat in the other chain and recieve the coins in the same address? I don't know. Just dump that 1 BCC for free BTC because it's going nowhere.
