It does not matter how much Bitcoin you sold. If you owned Bitcoin (BTC) PREfork under a private key, then you still own your Bitcoin Cash (BCC) in equal amounts. If you had 3 Bitcoin (BTC) prefork under private key, you now own 3 Bitcoin Cash (BCC). You have not spent your Bitcoin Cash (BCC). If you still own your private keys, you have Bitcoin Cash (BCC) waiting for you. :-)
