This can be said about almost any alt-coin.

The big hope for Bitcoin Cash now is that a lot of miners, blinded by the possibility of increasing their short-term profitability, will defect Bitcoin and start mining for Bitcoin Cash instead. That would be very bad for Bitcoin, and Bitcoin Cash would be the new king of the hill.

I don't buy that narrative, it will take years until Bitcoin Cash can achieve 4000 USD market price, just a flippening will cause disruption and lots of money leaving crypto in general. It will be a big loss for the miners, hence the bigger pools will most likely not support Bitcoin Cash with significant mining power.
