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.
BCH has been lift by those certain people and many big sites had given there words that they won't support the BCH and treat it as an altcoin only so many there's no point for us to think that Bitcoin Core will join to the BCH team since they had bitcoins to work with and there works for it doesn't stop since they surely want more adoptions to come with bitcoins so that the value will rise.
