Cryptocurrency anonymity is becoming increasingly common. Monero, Zcash, Grin, and others claim to have strong privacy capabilities. It's likely that many of these privacy features will be implemented in Bitcoin in the future. It may appear to be a good idea to go with an anonymous casino based on cryptocurrency. Once you've made your selection, take your time to make an informed decision, and then let loose and have fun with the advantages of a casino that doesn't ask for personal information.
