There are already tons of casino games that we could play using crypto you only need to know the website.
And there are also some people who use some online games to gamble and have fun for example tongits go and other kinds of apps too
OP asks about real casinos (think Las Vegas here)
For this, it is necessary that the casino accept cryptocurrency as a payment for chips.
I believe that there is no problem
But isn't this exactly the problem?
Just like with merchants not accepting crypto, regular "offline" casinos may not be willing either because they would have to deal with volatility issues. In fact, all such issues can be dealt with in an effective and efficient way (in a technical sense), but that requires extra costs which can easily make the whole thing not worth it (given that they keep their books in whatever the official currency is). And still more so when people willing to stake their coins can easily do that in online casinos (which is totally hassle-free)
Now, nothing prevents you from exchanging chips for dollars, and then buying cryptocurrency
I agree, but this is not what the topic is about
