I think there’s not much difference now between crypto and fiat betting, especially since the government started forcing platforms to implement KYC. Crypto was supposed to give full privacy letting us gamble anonymously, but with KYC in place, that kind of defeats the whole purpose.
A lot of famous and big crypto casinos require KYC too anyway so as said there is not much difference unless you are really using a complete decentralized casino then you would just prefer crypto for that to maintain complete anonymity. If you are not that strict about anonymity, you can still use crypto for privacy and for convenience.
