I opened my account through their partner and deposited $6,200. At first, I could withdraw funds a few times, but later they wouldn't allow me to withdraw anymore, saying that my frequent withdrawals were suspected of money laundering. As a normal investor, would money laundering involve such a small amount? Now they've sent me another email asking me to pay a 50% margin deposit. In the morning, they froze my account, and in the afternoon, they unfroze it.
