Well, it is a start and an opportunity for those who want to pay in btc to have the option to pay. This process is way better than that of El-Salvador imo, the difference between the 2 is, Brazilians will have the option to pay in btc, get used to the process and even have the time to access and analyze the process, unlike El-Salvador who just went straight to adoption without given the citizens the opportunity to be acquainted and validate its importance.
you may have a point on this. at least their people have time to acquaint themselves to crypto payment method and the move is not a drastic one. once some of them got a hold of using btc transaction and experienced the advantages of using this method, they can easily spread it via word of mouth. this marketing tool is a very good one as the government doesn't need to spend money. if more and more people will be satisfied using crypto payment, in time, their crypto users will grow. the el salvador's approach was like draconian one, why it was encountered by street protesters.
