in the end of the day it comes to users personal preference
maybe they'll have to sacrifice a bit of convenience and play on a DEX casino or even if centralized, without KYC
even if this means they lose the option to play some of the games or have smaller liquidity depending on what they're doing
There's no way someone will create a decentralized casino since this mean they're not gaining a lot profit due to decentralized, except they're asking a donation or someone willing to send more money than it does. Since casino is created to make the owner rich, that's why I say it's almost impossible, they're also need to create their own game without cooperate with other providers.
