I bet it will drop to zero in a few years. Especially when second layer solutions like lightning network and different privacy features will be implemented to BTC. Bitcoin cash is just a piece of shit and it always was so. 
it looks difficult with the nature of bitcoin which is still volatile if it becomes bitcoin cash will get a lot of response from other people, of course whether it is negative or positive, still it will be difficult to run because bitcoin is also the benchmark price of most other coins.
