you can register and trade without KYC but it requires KYC for withdrawal.
The exchange allows you to make deposits and withdrawals without KYC. This information is reliable, I myself have recently made several withdrawals from this exchange and they did not request KYC.
Thanks for correcting me, since you say you have withdrawn several times recently from BitMart without KYC, you are definitely correct.
Since I'm banned because of the country, I can't try the withdrawal, but I took my information from some people in a telegram group, but it seems that their information is inaccurate.
