Recently, when depositing via bank card, my card was frozen. So I looked for other channels and tried depositing 15 U via U. But the platform said it doesn't cooperate and doesn't allow it, and withdrawals under 50 U are not allowed. Then I found OKX and bound an external wallet. A platform I just started using insisted I submit some personal information. Where does OKX have personal information? Where is the transfer record with the platform? I contacted customer service multiple times, but they just gave me the runaround and won't actually help users. Forget it, I'm switching platforms. So disgusting.
