If offline casinos implement such a system, it will really be wonderful. And it will be really beneficial for the casino as with all the winnings, if they hold it long term, the profit value increases automatically as the price rises of crypto. Hence, it is really something that should be implemented. I think Japan might have some offline casinos that accept crypto.
but offline casinos that implement bitcoin as a payment method can have long term losses, you saw that until recently the price was $ 12000 and now the price is $ 8000, i wonder how offline casinos would do to avoid having big losses if they accepted bitcoin as a means of payment. A few years from now (maybe 10 years) when the market is very large and not manipulated and regulated, I believe offline casinos will be happy to add bitcoin as a means of payment.
