No,
they aren't a scam.
I sold my BCH for BTC, but had to wait 20 confirmations (just in case of 51% attack)
i was able to withdraw my BTC trade after the 25th block on the new BCH Chain.
just be patient.
ViaBTC good to go.
Did you read my post at least ?
I will not get my coins back. Not because they can't get them back, but because they will keep them using the fact that I made a mistake (like many others did).
