you can do what you wish...
if you want to make a profit then you have to keep your Bitcoin for more days. if you sell at the lower rate then definitely you will make a loss regarding this issue. so wait until a couple of weeks and see what will happen in the near future.
This is correct but at least to me holding seems like the best option, if you hold you get both BTC and BCC then you sell your BCC and get some free profits, after that the only thing you need to do is wait for the price of bitcoin to recover, if it went down at all and then everything will be as it was before the hard fork except you will have some additional profits in your pocket.
