MEXC has gradually introduced selective KYC processes. Some users have been prompted to complete KYC, while others have not, leading to some confusion. It seems the KYC enforcement may depend on region or triggered risk factors. While there has not been an official announcement of mandatory KYC for all users, the exchange has started to align with global regulatory pressures.
I heard about the mandatory KYC. But KYC should not be a problem as many exchanges have KYC now. I am verified on Binance, Bybit and some other exchanges that I am using. About the KYC on Mexc, I still check my account and I saw a withdrawal limit of 80 BTC per day for unverified users. I think those that have to be verified are countries that make KYC compulsory for the exchange.
