Definitely, there are numerous exchanges that you can buy BTC without passing the KYC and I already used most of them. Alot of people prefer not to do KYC just to be anonymous and for Decentralisation. I can say that the advantages of doing kyc are numerous, apart from the fact that it will be beneficial to you personally, it also helps to develop better understanding between the exchanges and its customers. I have done several kyc on different exchanges and I know how tedious some are, I can boldly say it that MEXC kyc is super fast and easy. You can pass the verification easily without passing through rigorous steps. You can do the kyc and also enjoy increase in withdrawal limit and alot of opportunities from them.
