I was making a withdrawal at Expert Option Fx, and it was said that I had triggered the exchange's risk control. The customer service said that a capital verification of 10,000 US dollars was required before it could be unfrozen. I deposited it, but they said that the transaction flow rate was not reached, and they asked me to top up 50,000 US dollars. Okay, it feels like a bottomless pit, and I can’t get it out no matter what.
