Thanks for the response. I do understand that using such exchanges is a risk, but there was a reason to use this exchange in the past.
Yesterday they wrote me this:
Hi, your operation triggered our system risk control alarm, now it is under manual checking, will withdraw for you soon after checked if no problem. Pls wait patiently. Thanks for your support.
It's been 3 weeks that the withdrawal hasn't been approved yet? and I am sure they froze your funds for a long time, I don't even think how much I can wait manually if this withdrawal can be verified, maybe this is just their reason for saying so and there is no other way unless you continue to urge it to be verified immediately.
What I'm afraid of is when other big withdrawals also experience the same thing, namely manually and waiting until an undetermined time, but I am here you hope to get your funds safely.
