Yeah I am in the USA which bans betting with Bet Fury.
I also hope to move from the states to Costa Rica which will all me more flexibility with casinos and exchanges.
Most crypto casinos advertised on Bitcointalk possess Curacao gaming licenses. I don't remember ever seeing Costa Rica on the list of banned territories. Although, I have to be honest and say that I haven't really paid attention to that country. I am more focused on countries in the EU and you will always find the same ones being banned: France, Germany, the Netherlands, the UK (not EU anymore, but still), etc.
It is funny how in the US some casinos are still banned these days. I wonder why they do that, even though they have casinos in some states, this probably has to do with taxes and because it is online? some day when fully decentralization exists, then there will be plenty of options.
The US is a legal nightmare when it comes to gambling so online casinos tend to ban US citizens altogether because it's the easier thing to do. Each US State has their own gambling laws. Gambling isn't necessarily banned but you often have to physically be in the State whose casino you are playing at. Since that isn't the case with offshore casinos registered all over the world, you can't play there.
There are also laws banning payments to online casinos in certain instances. Not sure what that law says. But if you can't deposit money into your casino account, you also can't gamble. So even if you don't ban online gambling per se, you get the same result by not allowing your citizens to send money to casinos.
