Have you dumped your BCC yet? If yes, explain the following:
1) What method did you use to dump it? Did you get the split from a Bitcoin Core wallet or other method to store your private keys?
2) If you selected an exchange, in what exchange did you send your coins to receive the split?
3) Have you sold yet? If so, in what exchange and how much have you sold?
Here are the steps I followed:
1. Move BTC from existing address A to another one *after* fork has happened. Now we can worry less about compromising private key of existing address A.
2. Use Electron wallet inside a virtual machine, imported private key of address A. Soon your BCC balance will show in the wallet.
3. Move funds to ViaBTC (I used them, but you can use another)
4. Sell them for BTC.
5. Wait for 20 blocks for your deposit in Step 3.
6. Withdraw BTC
7. Profit!
(for multiple existing address, the procedure is pretty much the same).
