This is the reason why Brazil has a good ranking in the Cryptocurrency, in fact, a lot of ICO and crypto related projects are based in Brazil , so Brazilian companies should target these as their consumer-base because they have a ready market on Brazilians.
Any source to support your claims that lots of crypto projects are based in Brazil? I've been in crypto space for almost 2 years but I can't even name 3 projects that was based in Brazil (ICO, startup, or something similar). Most crypto startup are based in EU, Singapore, several Asian countries as far as I'm aware.
