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.
For land based casinos accepting crypto would be a good feature that would attract new audience to their premises. How to avoid possible losses? That's easy. They can accept BTC or any other crypto in exchange for casino chips at an undervalued exchange rate, say, $105 worth of BTC for a $100 chip, and exchange crypto for fiat themselves right away. It is very unlikely that they could lose anything this way. And for crypto holders wanting to gamble, 5% is nothing
