so what is bitcoin cash?

you're buying into the bullshit that Roger "Self Made Millionaire" Ver feeds you - he is just in it for personal gain in the end of the day.

I would never invest a dime into bitcoin cash - and a lot of people share that position - they did more damage to crypto currencies than you could imagine.

If he has his own vision then fine, create your own currency, start with a new chain, just like everybody else does. forking a chain is morally reprehensible, it it set a terrible precedent. Trying to "attack" the chain you forked from is morally reprehensible. This is the number one problem with crypto right now and you can thank your friend Roger.
