They need to know crypto casinos or sports book so they will not face any problem.
When gambling in crypto is possible because we can do it anonymously, we should see it as an opportunity to bypass our country's restriction on gambling, I think it's easy to do that, just use VPN to mask your real IP address and you are good to go, these people are smart but not so smart.
Yes it is easy to use VPN to hide their IP, but the thing is does this site will allow people to use IP? or to have different IP that is far from the previous one? that will result them from being banned if it is prohibited. Maybe it is sad that they did not allow people to gamble or to use crypto, it can help their citizen as well, if they are concerned about addiction it is not beyond their responsibility I think. So for now they should obey law, soon they will use crypto again I'm sure.
