These are different questions. The casino can be legal and operate only with crypto. Or the casino can be illegal and work only with fiat. Therefore, if this is important to you, you should clarify both of these issues separately.
Unfortunately, I see that in recent years almost all casinos become legal in one way or another and the meaning of using cryptocurrencies is lost.
The question is very clear, at least for how I delivered it. What I'm talking about is if there's a
"crypto-casino" that is directly governed and mandated by the government in response to what I quoted above.
I don't consider the Curacao license as an example. If I'm not mistaken, gambling sites under Curacao don't have to pay any tax. It means these sites aren't directly mandated by the government. If a certain business, in any industry, is mandated by the government, they are subject to paying tax.
Again, anyone who has knowledge about this can correct me.
Here's the quote:
As long as there are casinos who will not require KYC then it's fine. But some government rules where to strict now in crypto operations that some websites like gambling casinos requires it too for their permits operation.
