Well for my view on KYC that you raised, I don't think that gamblers who dislike it are doing so because they don't wish their friends or relatives to know about their losses or profit. I think majority of it could be because the cryptocurrency system should be decentralised and everything about it encrypted. For example if playing with bitcoin as a decentralised cryptocurrency, while disclosing the identify behind it. That is the point and I think KYC goes against this principle of decentralisation which is the cardinal principle of cryptocurrency.
