It is spreading as a cancer. This month the central bank published a report saying that in August 20% of the Bolsa Família, the largest money transfer program for very poor Brazilians, was spent on these bets.
Out of the 20 million people that receive it, 5 million made bets during that month. This is 2 billion reais (about $450M) spent in a single month by the poorest Brazilians.
It's a cancer. Everywhere you go there are ads. The influencers, the biggest athletes and musicians are marketing it.
Although I tend to be liberal, this needs to be heavily regulated.
As a libertarian however, I break with the opinion of making consensual activities illegal even if they are self-harming. So I guess my stance is probably the same as addictive drugs. They could be legal, but come with the same labeling, warnings, ID requirements and age restrictions that come with a pack of cigarettes. We should probably be educating kids about the dangers of addictive apps like we once did with DARE on the dangers of drugs.
