I don't want to promote other casino here but to give you an example, have a look at rollbit. There is a global version of rollbit.com and if you visit this website from UK, rollbit.com redirects you to rollbit.co.uk, which has a different games and UI but belongs to rollbit. They did it to meet the regulations.
This is a good example and it makes sense that companies have to follow governmental regulations and they have to adjust their available services, products to users in different countries with different laws, regulations and licenses they got.
I didn't know about this model from Rollbit but it's logical if they actually did it. Obeying law and regulation will reduce a lot of risk for their business, the owners and can help them to expand business better and can maintain it well with time too.
This will be beneficial for the casino only if there are a lot of people using chips.gg from Brazil. At this point, we are just speculating the situation. It would be best if someone from Brazil can try to access chips and see if they can use the platform. If they can access the website without any issue, then we don't have to discuss just based on the news. Or chips.gg representative may share if they received any kind of letter from the Brazilian authorities.
I agree with you that it's better for Chips.gg company if people from Brazil can access the site, or a mirror of it, and use limited services and products from Chips.gg team.
However I disagree with you that Chips.gg company will only get benefit from their business operation ONLY if Brazilians can join the platform. They have users from many countries and if their business model is good, it works in all countries, and bring benefit to the owner team.
