This is could be a much bigger news that it looks like right now in the near future. When you consider that Brazil is a member of BRICS and kind of a "leader" in South America since they can convince a bunch of other countries in South America to do the same specially because they have good economical relations amongst themselves.
In other words in the following year or two we could see a lot of other countries accept bitcoin as a legal payment method...
As I postei in some other topic, this law is not what it looks like
It has nothing to do with payment method. This is much worse, and it is just old oligarchs trying to increase barriers to new players.
Tldr: bad, old, national exchanges trying to ban binance and every other foreign one that can offer a better service
