Although BCH is just a fork of BTC, you cannot underestimate its performance, it has a lot of supporters and the fact that it has a trading volume of nearly 4 billion dollars, when it is exaggerated, You can expect the value to increase significantly.
Yeah, even Bitcoin Cash is crap compare to the original Bitcoin. Still, they have a lot of followers and front faces at every exchange so I guess they will stay for very long no matter what.
