All nations listed above have good reputations for providing licenses to legit sportsbooks and online casinos. Costa Rica, especially, has licensed legitimate online sportsbooks and casinos.
Believe it or not, the fact is, some countries in the continents of Europe, America and Australia have different rules and laws for the gambling industry, whether it's a physical casino or online, it's something that many people know, maybe.
Different from the continent of Southeast Asia, the rules and laws in these countries vary, that's because they are mostly Muslim, so it's no wonder you don't find the gambling industry legally on the continent of Southeast Asia.
However, despite this I am happy to live and gamble in the continent of Southeast Asia, where many countries are there, online casinos are not banned and do not require, users gamble at the risk for themselves, legal is not and illegal is not, of course many states of the continent of Southeast Asia are not blacklisted online casinos.
