I expect Bitcoin Cash to go much the way of Ethereum Classic. It will continue to trade, but at a much lower volume and price than it's rival. I've heard some speculation about Z-cash merging its platform with Bitcoin Cash to create B-cash. That sort of consolidation may improve its performance overall, but I don't expect it can ever compete 1:1 with Bitcoin, and will probably remain around the current price of Z-cash in the low $200's moving forward.
