i saw a post here once asking about whether banning gambling will actually solve some problems. well even with gambling deemed illegal, it has not completely disappeared from a country. for example, in north korea gambling is illegal for its citizens.
but there are still gambling events that take place most often organized by some authorities or really rich and powerful people. i guess that making gambling illegal is just a way to make it less accessible to the general public but the rich always finds a way.
there was even a case where north koreans are targeting foreigners and selling them their own made gambling platforms.
North Korean IT workers created and sold thousands of illegal gambling websites to South Korean criminals to raise billions of dollars keep in mind that gambling is also illegal in south korea. so my point is, everyone eventually finds a way.
Exactly to ban completely the online gambling is totally impossible nowadays, cryptocurrency casinos makes it even more difficult as just using a VPN and a pseudo-anonymous wallet of most cryptocurrencies will probably bypass all the restriction put in place by the country wanting to ban gambling all together. Even in Saudi Arabia people gamble, yet they don't do it openly but only when they are at home, I have an ex colleague working there and he told me he and some other colleagues of him are gambling easily with just a VPN and cryptocurrency wallet. If it happens in such restrictive countries I doubt it is anywhere impossible to gamble, the only thing governments achieve with banning of things is giving criminals a way to make it more accessible to people for a higher fee and as such for them is just a business.
