~ Probably, you may look for a casino which is not accepting any kind of fiats including different payment processors. Because, when a casino handles fiat then it may start enforcing us to clear KYC at any time and most gamblers still hate it.
If the casino is in the jurisdiction of the countries whose laws regulate cryptocurrencies, they also at any time may require their customers to pass the KYC, even if there is no such requirement when registering an account. That's why you should be more careful when choosing a casino and be ready to provide your personal information at the first request.
i'm surprised we don't have more of this kind of application running on ethereum and sidechains these days
