For security reasons, many exchanges currently require KYC, of course this is good because to ensure that users are real and if a problem occurs it is easier to solve, but I don't like KYC because I think exchanges that require KYC are different from the concept of anonymous cryptocurrencies, and this is what makes me prefer trading on exchanges that do not require KYC and 2 exchanges that I think are good are MEXC and Kucoin.
