I can't speak for everyone, but I'm currently in SouthEast Asia(Philippines, specifically) and I'm really not seeing a "new wave" outside of Binance speculators. Heck, I personally haven't seen a single brick-and-mortar store that accepts Bitcoin.
This would mean that in Argentina you could open up a shop that could sell things for bitcoin and that is in the law, if it wasn't then they wouldn't be able to do that in this cafe neither. This idea itself is the thing that we are hyped about, not the fact that there is a place where you can buy a coffee.
