Coins are there ...
AHhhhh
Thank you . Now I don't know if the other wallet of BitcoinABC contains coins or not...
Thanks for the help !
What other wallet of BitcoinABC? You shoud have one empty wallet.dat when you first open the BitcoinABC client, then the copied wallet.dat from the Bitcoin Core folder which you should have emptied first (by sending your BTC to other addresses, to avoid problems). This wallet.dat that is now empty in Bitcoin Core, should show up with the BCH that you should have received during the split. You can send now these coins to an exchange to dump or whatever, but make sure that you did the step of moving your coins in your Bitcoin Core wallet to another wallet first because it seems you just copy-pasted the same wallet and didn't do this step.
