I have been reading that exchanges are not open to BCC deposits right now.
If your bitcoins is on a wallet / exchange where you don't have your private key and they don't support bitcoin cash, you're basically screwed.
Exactly. What I understand the OP to be asking is if he has his private keys stored somewhere, how can he now dump them. It is my understanding that none of the exchanges are taking BCC deposits right now.
Oh so its a waiting game at the moment, what do you guys envisage the process to be ? Download a BCC wallet import your Bitcoin Private keys into the bcc wallet then act accordingly ? What exchanges are likely to sell it or could you use cryptonator or shape shift to swap it.
