Your statement is completely right, but the way the question was asked, OP probably didn't know whether it was an exchange "that quickly implemented BCH trading." So maybe a better analogy is being in the frying pan and pressing the hyperspace button.

By the way, why would you need to wait to sell a BCH deposit? That confirms almost immediately, right? I could understand AML/KYC on a cash withdrawal, but incoming crypto is zero risk to the exchange.

Takes 80h to confirm because of the low hash rate on the fork.

Doh. I thought the fork code had a built-in contingency for a quick difficulty adjustment in case of slow blocks. Maybe I just dreamed that.
