On this basis, the most important condition that the user must ensure is that the casino has a valid activity license because this is more guarantee of rights in the event of any problem.
Crypto gambling sites licenses are overrated if you ask me. Why? Because those sites don't really have a physical presence thanks to which it's not easy to sue them in case we face any issues.
For example, just look at 1xbit. They have a valid license, but it doesn't matter since they are proven scammers who cannot be tracked down easily.
In any case, there is no guarantee of absolute integrity. Dealing with a casino operating under a valid license is certainly better than dealing with an absolutely unknown casino. At least there is room for legal accountability and judicial follow-up in the event of any problems or suspicions regarding the casino. Almost all honest casinos operate under an activity license and as we see here on the forum, they deal seriously with accusations and complaints from users in order to preserve their reputation and thus maintain the license.
As for the example you cited regarding the 1Xbet platform, as I recall, it has an activity license from Russia and the platform originally operates under a Russian company. Russia will not condemn any of its companies if the plaintiff is a foreign party, especially since Russia is a country with many hostilities around the world.
