In my opinion, it is very important that casinos have a license. Just think that in the real world, governments require casinos to have a license, so governments did not allow online casinos to operate without a license. So this means that an online casino without a license has a greater risk of being seized by the government and all funds will also be seized. Nowadays, it is useless to avoid KYC. I would advise the casino owner to get licensed to be in compliance with the laws
Definitely it is a essential things to the online casinos'S in case of gaining the trust from the user's and that is why the casino's are investing millions on the behinds of licence companies. Without licence a casino can also gain the trust on the net but it took times..
Anyway about the suggestion of your regarding getting licensed to this casino. I think may be they could be issues it that because of the being decentralized platform. Decentralized casino means the non-kyc casino and non-kyc also against the anti money laundry laws.
If they just get those license from a country which doesn't regulate much gambling then its still nothing since there are lots of license casino pull a rug pull scheme to their clients. What's more important here is the reputation they built in this community also their willingness to follow the suggestion and other things needed to take care especially for listening to peoples suggestions. Also people care about much on how their support response fast to the issue since most of people like to have active representative will solve their issues.
KYC thing is I think not an issue since people here now already know about regulation and those things want to avoid by legitimate casino since people nowadays is willing to comply if they asked to do this especially if they already gather good reputation to the community.
