Bcash is rising in value because it gets pumped by very few people. That's it! It will either survive as a useless shitcoin or end as highly centralized version paypal but with much less transaction per second, blacklisting, account freezing on certain exchanges and so on. We've enough of that in the traditional financial system already.
I share the sentiment that BCH is not experiencing organic adoption, just market manipulation. It's natural, since like BTC, most supply won't be sent to exchanges. For that reason, it's really easy to soak up the existing supply, then pump. I'm guessing a single whale with 25k BTC could have propped the price up before this pump.
