If the government legalized crypto currency in the country, of course the possibility of crypto being one of the payments for physical casinos could happen, but of course users would prefer to use fiat currency when playing at physical casinos because it is more practical in nature, except for gamblers, who have a lot of capital, of course, it will be very risky to bring a lot of money so maybe they will prefer to use crypto currency later.

That is why most gamblers carry their credit/debit cards instead and usually prefer to use ATMs before the actual game. As saying goes, when it comes to gambling cash is a king.
