Bitcoin Cash was deliberately split away from bitcoin by a team who thought high fees and slow transactions would eventually destroy bitcoin. It was deliberately designed to essentially be bitcoin, except easy to send, receive and transact with. But, I still prefer bitcoin tho when it comes to liquidity and value.
Bitcoin was growing for many years now BECAUSE it was cheap and easy to use / was onboarding all sorts of ppl and businesses.
Now check what happend over last year to BTC adoption speed?
The prospect is the key, and you cannot force ppl to wait and later use. Ppl are free.
BCH saved that initial momentum of growth.
Long time extrapolation looks very bad for BTC ATM.
