If you don't want to use a secured exchanges I'll recommend Binance becuase it doesn't need KYC. KYC exchanges are better to use because they know who you are and where are you from. Most of KYC required exchanges are more secured than those exchanges that is free to withdraw without any verification. KYC has an advantage to no KYC exchanges because in KYC you can withdraw bigger amounts than the no KYC required exchanges.
