In as much as I am no fan of KYC as I jealously hold my privacy to a high esteem I just have to admit base on how things are going KYC will definitely penetrate into all crypto-based platforms through by the coercive use of the instrumentality of the state by the government, like the circumstance of mixers it all was like a dream, if you resist you will be swept off the business environment, and these casinos wants to still be in business so they therefore have no alternative than to concur (I can't really blame them). So as gambler we can't escape kyc anymore, if it's not demanded today it will be tomorrow or next.
Casinos are KYC compliant and anyone who want to use their services must abide by the rules. I have no problem with KYC for casinos because I do not want them to be penalized by the authorities that regulate them for compliance failure but I totally avoid, any crypto related KYC submission like a crypto platform asking me to submit KYC. Never.
Gamblers need not fear so long as they are not trying to launder money. The rules are for the bad guys not the good guys.
