The site doesn't even have a license. What else is there to talk about
IMO I am thinking that's doesn't big matter because we already multiple of Big and successful decentralized casino site in this forum they also don't have the license and as we also know that in most cases, it is seen that decentralized casinos are not easily licensed because in many cases they go against AML policies.
The matter is here their site looks like a duplicate version of the Bitwinup if you just check that. I have also doubt about the certik audited but because of I don't know how to verify that the project or site is really audited by them I will no comment here.
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
