There is no problem with the deposit. The previous small withdrawal was successful, but the subsequent withdrawals were two times. One time the account was increased by 3. The other party asked to pay 5,000 US dollars to unlock the account and then withdraw the funds. After the payment was unlocked, the withdrawal was not allowed. It is said that the system detects that the risk account needs to pay a risk fund of 450,000 before withdrawing funds. This method seems to be very problematic.
