NEVER EVER send your private key anywhere. Move yout Bitcoins to a new address before you do anything (paid 50cent in fees 2h ago).
Wait until Coinomi supports it and sweep the now empty private key which held Bitcoin due the fork. Did that with Bitcore now 20$ per coin
, that's a clear warning and I'll heed it. I don't understand what "sweep the now empty private key which held Bitcoin due the fork", sorry. Where can I bone up on how to do that?
Also, once Bitcoin Atom puts out their Atom wallet, wouldn't that be a good way to get the BCA and store it?
The exact procedure varies by what wallet you're using.
I'll explain briefly using bitcoin core. If you need further clarification, feel free to send me a PM.
First, you will ABSOLUTELY want to move your Bitcoins to a new address, maybe even a new wallet! Because if you do this on a site like Coinami (who are honest, but still...), you are exposing your private key to the internet. It could be intercepted, and it could be used to steal your shit if it's still there.
I honestly would WAIT. Wait until the core wallet is released. But if you MUST use Coinami, follow their instructions after doing the above and the following.
First, export the private keys of every bit of BTC you have in your wallet currently as of the fork block. (actually second, because we assume from here forward that you have sent your BTC to a safe place). You do this in bitcoin core by clicking on "help", then going to the console.
In the console, you'll need the address(es) where your btc resided at the time of the fork. For each address enter:
dumpprivkey "address" (yes, you want the quotes).
Copy the output to a text file. When you save the text file, it's a good idea (not mandatory) to encrypt it. But after you get your BCA, you must NEVER use these addresses and keys again!
Now, assuming you wait for the Core wallet, get it synced, then go again to the debug console and for each key issue the following:
importprivkey "privatekey"
This is the slow, hard way, but it works. It will rescan the blockchain for each key you put in, and the coins will appear in your wallet. Been through this twice. There's and easier couple of ways. Well, less time consuming. But this is the safest.
However, if the Dev team has also forked Electrum and has a version of that in play, you can import the keys in a batch (Electrum wallet tells you how), and it will happen much faster.
Note that in both cases here, you still control these keys. But I would still send the coin to a new address, cuz why take unnecessary risks?
If you do use an online service, ABSOLUTELY IMPERATIVELY MOVE THE COINS to a new address, IMMEDIATELY. One Bad Actor and you're out of coins. And as noted above and by others, move your BTC BEFORE doing any of the above.
Hope that helps
