IMHO they both must be delisted from all top exchanges like all other aggressive forks that saying that they are true chains)
That is happening . i saw lots of news that says that exchanges are now de listing bcsv .l dont know why this coin is so controversial ? Is this s fork ? If it is then there are many fork coins out there including bitcoincash but why they dont de list bch ? Bch is also controversial before but until now bch is still alive and going stronger .
I dont think that this coin bcsv can have a bad effects from the market . people think that itl cause bad effect because they think that it can be a rival of bitcoin but that was normal . every single day there are new coins that are being created but people dont even care on them .
