The Brazilian people are the biggest gamblers in the world, spending around 4 billion dollars a month on bets, so the Brazilian government saw this as a good opportunity to collect more taxes, making casinos regulate themselves and have authorization to operate in Brazil. I believe that all good casinos will have to adapt, but amateur casinos will have some kind of problem. It is a global trend for casinos to comply with the rules established by governments, and this is what will happen sooner or later in all countries.
I am not Brazilian, but since I am Mozambican and speak Portuguese, I have been following the news from Brazil and from what I am seeing, Brazilian laws are moving in the direction where international websites must have a physical office in Brazil. I have come to this conclusion because of the recent closure of Twitter in Brazil. The president of the Supreme Court ordered Twitter to be closed because it had not obeyed the law that it must have a physical office in Brazil, and Twitter had closed its physical office and no longer had a representative in Brazil. I believe this is a path that in the future will require international betting houses to have a physical office in Brazil and have a legal representative in Brazil. This would mean that Brazilian citizens would no longer be able to use casinos that operate without complying with these conditions. So in my opinion this is all heading towards very strict laws that most casinos licensed in Curacao will not comply with.
The vast majority of casinos in Curacao will not comply, but I still believe that the most reputable and largest will comply, even if they have to offer fewer services to Brazilians than usual, because the gambling market in Brazil is the largest in the world. No casino (I believe) would like to lose space in this lucrative market. The Brazilian people are quite addicted, gambling has always existed here (I'm Brazilian), such as "jogo do bicho" and slot machines, the difference now is that the vast majority are online...
I looked for information; maybe the whole reason for the closure of so many casinos in Brazil is that according to statistics, every ninth Brazilian plays in a casino. Moreover, every fourth person who received financial assistance becomes an addicted gambler and loses everything, right down to the contents of the refrigerator. These are truly threatening numbers.
I would begin to respect such a government that wants to protect its population. But yes, I know that forcibly explaining something to someone who is not ready to stop gambling is useless.
Maybe the way out of this impasse would be to better ensure the standard of living of people so that they do not place their hopes on casinos but are provided with a guaranteed decent job and, of course, a salary.
I don't believe that the Brazilian government wants to protect its citizens. I'm almost certain that they want to collect more and more money from taxes. The Brazilian public sector has exorbitant spending, but since it's a populist government, the order is to spend more and more on aid and to do that they need to collect more and more...
