Benefits
Privacy: Many crypto casinos require minimal personal information, allowing for more anonymous gambling.
At first, they won't ask a user to comply with KYC but eventually, they will. That's known already in the community when most of the known casinos have started asking for verification, additional, or a beginning process.
It might be beneficial for starters but expect and see to it that everyone is going to be asked later on. Who benefits the most from this are the casinos and the regulators, they're using it to trace dirty funds that are used into laundering with the use of these casinos.
Anyway, this thread should be on the
Gambling discussion and not this section.
If the casino is licensed, expect that they will require you to comply the AML/KYC protocol as it is part of their compliance to their licensing authority. I believe, this is already the common practice already among gambling sites in order to penetrate the mainstream market. As this business is already under the regulation of the licensing authority, they need to abide the laws promulgated to operate this business.
