I think that BCH will still stay in future simply because EGO in people and their will to win and show others that they are right "being true bitcoin" it has good supporters such as Roger Ver himself with other influential people around it. As long as those people are on top there you shouldn't worry about BCH, simply because if you have influence you can make some place for your coin, take a look how fast they went on coinbase but it took ages for litecoin...

In my opinion their community will support it and have large amount of people.
