Before KYC compliant casino are much hated by gamblers but now since they understand now how regulation work on casino people slowly accepts that they need to provide their KYC details so that the casino they are playing can make sure that they are following the requirements asked by those legal authorities to have.
Then table shift and people now doubting to engage with non KYC compliant casino since many afraid that something might happen since they are not complying with law. There are so many scams happen and I think that add to the fear of people to use new casino which doesn't ask KYC. That's why at the moment those casino owners planning to launch their business here is to try to operate with license since sometimes this is what people ask since having a license to operate is really good to be seen by a lot of gamblers in this community.
The no-KYC part from crypto games was one of the biggest selling point in the beginning and the reason a lot of people joined them also. Personally, I don't have an issue with doing it as long as it is a reputable casino that has proven themself over 1-2 years. A license helps for the credibility, but is also no holy grail.
