I'm not considering selling neither my BTC nor my BCC. Why? Because I'm not a trader (most traders lose money in the long run) but a believer in Crypto Currencies, especially Bitcoin.
I'm not skilled or technical enough to have the prerequisite to know which one will make it or break it. Luckily I now own an equal amount of it. I have not invested into BCC, I got it for free. There are three possible scenarios.
Bitcoin will "win" and BCC will go to zero or close to zero. I have not lost anything holding BCC too
Bitcoin will "lose" and BCC will win. I own an equal amount of BCC and therefore I have not lost anything
They will both co exist at different pricing like they currently are.
The combined price of BTC + BCC is right now at $3172 USD.
That's why my non professional advice to most people is again once again to just HODL. Never sell your Bitcoin or forked Bitcoin cash or whatever they are called in the future. You've been given a free chance of being hedged. Take it and hold it.
Right now it doesn't seem like Bitcoin is suffering that Bcc is gaining fast. All alt coins are going up as well, and Bitcoin holding steady. Seems to me like new money is entering the Crypto Market at this point, and that we will see another lift in BTC as well soon as people take profit from their alt trading. Do not take my word for it however. I'm not a professional and don't consider my advice that.
