There's a trend in casinos to add stablecoins. Stablecoins would make it much more easier for traditional gamblers to move to crypto gambling sites. Most of the crypto casinos provide better house edge than traditional casinos and some form of gambling are still exclusive to crypto users.
I've seen on most casino sites that people are asking how to buy and sell crypto and how it's value is determined. They'll feel easy gambling with stablecoins.
