I check Trustpilot for BitMart and MEXC it have really bad reviews in last time? how can i find out if i can trust a plattform?
How can you trust anyone's reviews when choosing an exchange? If I, for example, write that I have not had any problems with MEXC, and someone else writes that his account was blocked on this exchange, who will you believe? You can be told which exchanges work without KYC, but you have to choose for yourself.
P.S. BTW, on MEXC, withdrawal for unverified users is 30 BTC per day. Will that be enough for you? If not, you will have to go through KYC.
