They first let you deposit and trade on their platform and then one time when you try to withdraw a sizable amount, they will block your account and ask for KYC just like the shit HitBTC exchange. I have seen quite a number of people have this same kind of complaint which make me believe there is some truth to it.

So most of the victims are left with no choice but send the KYC documents in hope that the money can be withdrawn but guess what? It doesn't work.
Given how scammy the exchange is, I would personally never send them my documents even if I had a few bucks locked in there.
