Fight back. Let them know that bitcoin cash is not a dying alt coin but a competitor to the thrown.
it's just another alt and all alts are getting destroyed. if bitcoin keeps it up and introduces some working second layers soon then the alt party could be over for a long time. it'll come back but i don't think almost all alts will ever reach the all time highs they achieved against the btc ratio again, especially this one.
if you're into dollar gains then you're still fine.
i'd say maybe the prime factor in bitcoin going mad is koreans falling out of love with bcash for now at least.
