I posted about Brazil a few days ago hehe
There is a survey that shows that Brazil is the country with the most betting sites access in the world
And in the volume ranking, we are the 9th country in the world
However, you have to consider that the country's currency is very devalued against the dollar and the euro, which makes quite a difference in the end.
It's very easy in Brazil to come across someone playing the tiger game or making sports bets
I would venture to say that betting is a fever in Brazil
I think 15% is a real percentage
