Good going Brazil. People might have huge demand for bitcoin in the future, as brazilians have a declining currency, somehow stringent capital controls, spend many hours on the internet and most people own a smartphone
That is pretty nice that Brazil already has that many stores that accept Bitcoin but Brazil also is a big country.
I think that Bitcoin has to focus on other countries as well because they have not reached all of them. 
I think bitcoin is going to be better in Brazil because of that large country bitcoin is able to make adoption with that country. And for sure the people
there are already enjoying the use of bitcoin and since the population of Brazil is big they are able to make some good transactions there and as they shop it is very convenient at all no need to bring more fiat.
