I kept my BTC in Bittrex so I would be able to trade BCH as soon as they enabled trading. I think in 6-12 months there is a good chance BCH will have some use and value but not quite like Bitcoin. I imagine BCH going the way that ETC did when ETH forked from it.
I day traded BCH for 24+ hours and decided it was best to pull out, re-invest my profits elsewhere and way for the price to decrease before re-buying in. I believe the difficulty adjustment algorithm should've kicked in already which is why the price has decreased so much. But I think it will still go lower than it is now.
