This must be the reason why there is a pump of BTC price in Brazil. I'm not from the country but I just read it on the telegram channel. More and more countries I think will come to recognize crypto. War against cash started long years ago but it's only now that it becomes very visible in economic trade while some countries prefer to recognize Digital Yuan.
Slowly bitcoin began to spread and was recognized by countries of the world as a better payment alternative, but even though bitcoin is now starting to be adopted as payment, I don't think that will kill the use of fiat money as official money in a country, I say bitcoin and fiat will be able to go hand in hand in building growth and creating a more diverse payment mechanism in a country like in brazil, the use of bitcoin will of course have a big influence on the brazilian economy and a positive impact may also be obtained by fiat currency later, now brazil has take innovative steps and hopefully they will be able to get a positive impact from the passage of the law so that in the end other countries will also follow Salvador and Brazil steps to be open for bitcoin or other crypto.
