Here currently you can't have BCC because only btc can be handle by you with the ownership of the private key .
But probably your question will be better after the fork splitting after the 1 August ( chances are both to split or not ) .
Here ig we can take example of the ETH coin fork then we can say that both of the coin will be useful , because here
ETH and ETC both of them have values at about 0.07btc/ETH/ETC  coin .
So may be in the starting the value of the splitted coin will be low but it will be more better for us to keep everything
And wait until we reach at a best price and then make money in bulk  ( like those who bought btc at 3$ and now selling ) .
So we have the coin like BTC which will be available to buy at very low rate .
