Another KYC related case? This one involves a small amount which implies that he was flagged for something shady or it could have just been a system error. Whatever the case, he needs to stay patient since there's nothing else that he can do.
Also, he needs to update the status of his case in this thread itself instead of forgetting about it.
He only mention 90$ since it’s his profit but the total money involved on his account was 790$ which 700$ is his original deposit and 90$ is his profit. To summarized, the current amount that Duelbits temporarily holding in his account was 740$ due to the KYC while 50$ was already withdrawn earlier before KYC.
I think this is just a regular KYC probably due to his withdrawal pattern after profit or regarding the method on how he get that profit.
