I have fully synced Core wallet (135gb). How can i generate BCC?
What I did was backup my original Bitcoin Core data directory and create a new folder where the Bitcoin Core data directory is located, named Bitcoin_BCC for the BCC ABC client. Then open the BCC ABC client with a shortcut that has the -datadir parameter pointing to the location of the Bitcoin_BCC folder you created. Otherwise the BCC ABC client will default to using the Bitcoin Core data directory and it will overwrite the Bitcoin Core client files.
When you are ready to claim your BCC coins, open the debug console on Bitcoin Core the wallet and export the private key of the BTC address with the balance you want to import in to the BCC ABC wallet:
Close the Bitcoin Core wallet, open the BCC ABC wallet and import the key you just exported with:
The wallet will rescan and import the balance from the BTC address to a BCC address.
To safeguard your original BTC coins in the Bitcoin Core client, transfer the balance to a new wallet. Rename the wallet.dat in the Bitcoin Core data directory to wallet.dat.old and then open the Bitcoin Core client to create a new wallet. Copy a BTC address from the new wallet and close it, then rename the newly created wallet.dat to wallet.dat.new. Rename your old wallet.dat.old to wallet.dat again, open the Bitcoin Core client and transfer the BTC funds from the old wallet to the new wallet address you copied.
