Just check how Bitcoin Cash is being mined. When the difficulty is high, almost nobody except ViaBTC is mining it and there is one block found every 2 - 4 hours. Then when the difficulty drops because of the low hash rate, all other miners jump in and rape it for quick profit, with block being found every 2 minutes or so. This is repeating over and over again. And the miners are just selling the easy-mined BCH instantly to buy BTC.
I'm pretty sure BCH will just slowly die over time.
It is very obvious to anyone that bitcoin cash has only been created to benefit the miners, this is why bitcoin cash has so little acceptance with the average user of bitcoin, if people actually thought that this was an honest attempt to create a new and better bitcoin then I think more people will use it, but since it is so obvious this is nothing more than a way to get money, most users do not bother with bitcoin cash.
