Countries that banned gambling wouldn't ban it for no reason. I believe that they have huge reasons for banning gambling in their country regardless of the huge taxes that they could get from it. Once they ban it, I don't think they aren't firm with their decision. Banning also has pros and cons in each country and I'm sure that the government focuses on the cons that made them ban it.
You can defiantly ban gambling in a country like placing ban on casinos and blocking online casinos but there is no way you can ban crypto gambling. The biggest pros of crypto gambling is that it opens window of gambling for people living in gambling restricted region. But the other side of this advantage is that kids under 18 years are also getting addicted of gambling. I would say crypto gambling has more side effects then good effects.
People would never ever learn and instead of saving up those money or funds for something better or priorities.They do instead spend it up all in gambling which is something i dont see for it to be that worth i would
say on which you are doing hard work just for spending it all in an instant which we know that this isnt something that ideal specially if you do have responsibilities specially on having a family.
gambling is for fun and never ever tend to go beyond the border line specially on spending up money which is more than that you can afford to lose.
