I'm curious why you chose to use the term "bcash" to refer to BCH. No exchanges or mainstream projects use that term to refer to BCH. As far as I'm aware it's primarily used as a pejorative, so it seems strange that you'd use it here.
As far as BCH's additional value: I'd suggest researching the block size debate. This debate is BCH's entire reason for existing. This article [1] from 2016 by Mike Hearn contains a good primer on the block size debate itself. He ended up quitting development of Bitcoin, but others decided to raise the blocksize limit - with or without the majority, thus creating BCH. Succinctly, BCH is the continuation of big-blocker's vision of the Bitcoin experiment.
