I don't think BCH is ever going to be worth much of anything. There are already way too many altcoins (and bitcoin clones) on the market for anyone to stay interested in them for long. They'll get pumped and dumped from time to time, but I've predicted many times before that most are headed towards zero. Bitcoin has a huge community and merchants who actually accept it for payment, and that's why it'll stay alive. The rest of the shitcoins and clones don't stand a chance, which is why they tend to drop while bitcoin itself maintains value.
