all the useless altcoins disappear sooner or later. and bitcoin cash is no exception.
I think that BCH will good when: remove EDA and tranfer DA (like Bitcoin).
This algorithm is only suitable when Bitcoin Cash inherits bitcoin's difficulty on 1.8.
the only reason miners added EDA was to make profit by playing it. and they have done it perfectly so far and made a lot of profit from doing it too.
they won't remove something they want and they added themselves.
