KYC with MEXC (mx-yybtc.top) is a nightmare. I submitted my ID and proof of address. They rejected it and asked for a utility bill. I sent it. They asked for a bank statement. Then they asked for a selfie with the ID. Then they said the selfie did not match. I gave up.
Pros: Tax reports included|Multiple order types|Low minimum deposit|High security standards
Cons: None so far|Withdrawal takes 1-2 business days
