What happened:: I deposited 0.05 btc and exchanged into USDT, withdraw-ed it, and deposited another 0.2 btc. exchanged into USDT, but when i try to withdraw they locked my account. Withdrawals are temporarily disabled on your account. Please contact us via this form. during the long time, I provided all my documents (passports), driving license, proof or address, selfi photo, and much more documents. and later they asked for source of funds and documents for person who give me the bitcoin. this was crazy impossible request.
