It probably still pumped like another coin just like how old coin pumped, but i dont know how long bitcoincash would stay on the market since its purposes isnt needed anymore, BTC with its Lightning Network already a good combination.
from this ATH 4 years ago
All Time High
Dec 20, 2017 (4 years ago) $4,355.62
I think this is a very far fall from this Bitcoin copy cat (bitcoin cash), and i believe that this won't come any near these days of us.
I may be wrong but I really don't see anything good in a coin that claiming to be original Bitcoin but cannot prove anything .
