KYC exchanges are exchanges that guarantee the safety of their users, there may be some exchanges that do not use KYC, but as such these exchanges are less secure, and look un professional, I really like KYC exchanges because they are of good quality and professional.
P2P exchanges are the only way to convert your fiat into bitcoin. 90$ of these exchanges require KYC and provide a built in escrow service. Unless you are want to avoid Kyc and take a bit of risk, you may try other methods. I am using binance P2P without any issues to convert my fiat into btc or vice versa.
