Nope, you must open bcc wallet and claim your bcc first with private keys from your btc wallet, then you send them on bittrex or whatever and sell
Correct me if i am wrong)
I'd personally never import my private keys into some stupid fork.
You never know, seen too many hacker, frauder, lier and scams to trust a new fork with all my money.
You never know if they didnt make this fake fork only to collect all bitcoin wallet and then dump all of you guys money.
I believe this is why you send the coins to a new wallet on the Bitcoin chain first and then you use private keys on the chain that forked. Then there will be no coins leftt for anybody to steal in the wallet.
