Maybe we can’t totally skip the regulations and that’s why most of the gambling site today slowly implementing the KYC, though it kills the purpose of being anonymous but we have no other choice but to follow or else you’re still with the site that didn’t require any KYC. Time will come, we will see of other countries will continue to regulate cryptocurrency, if this things happen most probably KYC sill become a major problem of many gamblers.
Which one have a purpose to being anonymous? Roobet never wrote anything that their casino is an anonymous and never collect any KYC from their users, Satoshi a creator of Bitcoin, never wrote Bitcoin is an anonymous, but it's pseudonymous. If you talk about Monero and other privacy coins, you're collect since their purpose are being anonymous currency. But most of casinos didn't accept it due to anonymous and harder to trace the transactions, origin etc.
