I agree that BCH does not carry an innovative idea. I believe that it was created to attract attention to bitcoin. This is a classic example of the phenomenon of Pump and Dump, because the course jumps are similar to artificial inflation and collapse.
I do not know if this coin is related to bitcoin. But as far as I'm concerned, with the name it may be set in the hope of gaining trust like bitcoin. So naming is slightly the same (my guess). Maybe it has more features and smarter we have not explored.
