I don't give advise on how to trade, but just my view. In my opinion the value of BCH is driven on fake hype and LTC is a way better coin for daily payments (more used, longer track record and cheaper). Beside that I think that Bitcoin is way better in everything, except for the high fees that was the case for a while, but (temporarily ?) resolved now. The only advice I can give is: Do your own research and use multiple sources, the best thing will be obvious.
