No KYC is really a good feature but it means also that casino doesn’t have license to operate legally because this is a requirements by license provider.
Why do you care if they have a license or not?
IMO stupid laws should be ignored and fought, and this is one of such stupid laws, so I'd really like to see more no-KYC casinos. KYC equals to treating every client as money launderer and making them go through all these hurdles just to prove that they're not. It's completely stupid since real money launderers are less than 1% of all clients of the casino, but the other 99% have to be x-rayed.
I'm with you in not liking. A license really doesn't mean anything other than problems for the player. The casino just grabs a license at another jurisdiction when they have a problem. FJ, BC.games and Stake have all lost licenses recently and they just use a license from a different country.
