Privacy: Many crypto casinos require minimal personal information, allowing for more anonymous gambling.
as I know gambling can not be anonymous, unless you intend to cheat or something detrimental, currently gambling also requires KYC if you want to make a withdrawal in a certain amount that is definitely above the normal limit, you must do KYC. crypto gambling that does not do KYC can be questioned for its credibility, those who do KYC still have fraudulent gambling, let alone those who do not require KYC on their gambling sites
I don't want to repeat what he said but that tells it all that it is possible now to gamble anonymously with the help of crypto because some or most of them are decentralized. Cryptos are invented not because of the cheaters but it is to counter the centralization system which can suck. We can't only avoid that cheaters are also taking advantage of this new technology. They still can get caught anyways and if not, for sure they still can get a bad karma.
Cryptos are not new and eventually, centralization also joins here, so as you said, there are now some gambling sites who does require a KYC but I think this is also to protect the consumer from the bad guys, so they are still helpful somehow.
