I just want to give you the warning about their reputation in the recent times is not good so better choose other trading exchanges like Kucoin which still has no KYC trading feature if I am not wrong.
Kucoin is a centralized exchange but it allows trading and withdrawing when you don't want KYC, but you can only withdraw up to 1BTC within 24 hours with a non-KYC account.
@OP I check the screenies and there's no typo in there. The level two limit also shows $500k but you can try confirming things in their customer support.
