Already someone said Binance is the top exchange. I agree with him but their support is not friendly. Without support trading experience is good. Even I have a running issue with Binance, I am not getting SMS for 2FA in my phone number and that's why I am submitting my information using their system but they sent me a Failer verification email where they had said: "The reason: Cannot upload tampering photos". I am totally surprised. I am giving them my live photo using their verification system. why are they saying like that? anyone can tell me?
