I'm not convinced Bitcoin Cash has a strong future - I don't see what uses it has over Bitcoin. What's going to drive further appreciation of BTC is more mainstream adoption, which is starting to happen for Bitcoin. I don't see how bitcoin cash makes up that ground.
Thank you for your comment. There is no question that BCH is not a match for BTC. On one hand the good infrastructure that it has is an advantage but yet there are lots of limits. At the same time a few minutes ago Japanese exchange group has officially accepted BCH. We just have to wait and see what happens.
