What do you mean by BASIC KYC requirements? and also why need in your first site to provide KYC when in second site does now? can't you make it both not asking for players details?
I think it's because the gxgbet have license that's why they require basic KYC as stated by gxgbet while gxgcoin does not have license so it does not require any KYC. I can't access the gxgbet.com due to being one of the coin that is restricted and gxgcoin.io is accessible to me. I agree that it is much better if there's no KYC needed as it is what most people wanted. Even some known gambling sites may ask for KYC if they found your account being suspicious.
