Most of them are now requiring KYC, kucoin was like the last exchange standing that don't ask for kyc but with some hot news about them, for sure that they're going to be tackled by the government. Those that don't have kyc right now are the dexes but you know that many of them have security and liquidity issues. To understand the situation right now, it's hard to find an exchange that's 100% not kyc because if they do now, they're going to change their policy and will become 100% kyc compliance.
