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.
Probably because they have less capital and maintenance compared to the traditional casinos where they maintain the place and they have a a lot of employees to play. Starting an online caisino does not need a big capital, so we are seeing a lot of online casinos and that makes the competition better in crypto, but this will only serve gamblers which are fan of online betting, not on the gamblers who like to play cards in a traditional casinos.
