The El Salvador thing seems like an incredibly silly thing to me - almost like a
PR stunt to get more attention? The reality is that the transaction costs for Bitcoin are so high - especially compared with transactions in a 3rd world country like El Salvador - that this doesn't make *any* practical sense? In order for something to work with a small 3rd world country, it would have to be robust, stable (which it's not), and also very, very cheap to process transactions / micropayments. Bitcoin is the opposite of this. Plus who in a 3rd world country is going to know / learn about Bitcoin and actually use it to buy groceries?
Basically, all of the articles I've read on this topic have pretty much said the same thing...
