Regardless of their status as new or well-established. An online casino must have a license to be able to operate in a country. For example, if the online casino targets the UK market, you need to obtain a license from UKGC. Each European country has its Gambling Commission, therefore the first thing that new online casino has to do is getting a proper and legit license.
While getting a license is a must, not all online casinos obey the rule. For those casinos, we just list them into the blacklist categories and we do not recommend any players to play those blacklisted online casinos.
