I think the best way is withdraw the btc to my wallet or deposit them to some exchanges that support the BCC, right? I do not know much about the hard fork.
The best thing to do according to me is to move your coin to bittrex or some exchange that support the 1:1 ratio of bitcoin and bitcoin cash. Bittrex is giving BTC and BCC then why not should we take the advantage of it. The BCC we get after the fork will be on exchange which gives us the advantage to sell it before others at a higher price.
