I think I'm going to just hold the coins that I could convert to BCC. It's probably going to tank immediately, rebound a little, then super tank. But come September or October I think it will come back up again when the "2x" part of Segwit2 comes into question.
It's interesting competition. Those who don't like Segwit can just leave BTC now. Also those who still have miners in their attics will probably pull them out and fire them up for a little while. When the cards are played, there's a good possible chance that BCC might have similar value to BTC one day.
