Who really says it "failed? I mean its still a legal tender and people could use it if they want to and thats all that matters, isn't it?
It still remains the official legal tender in El-Savador and there have not neither has there ever been any official statement stating the reversal of bitcoin as their legal standard, then i asked myself why the worries up and down from other governments and those that couldn't deer take a common risk just like El-Savador.
I'd say that's a good introduction and imagine how all those people who cashed out right away are going to feel when in a year or so that same $30 is worth something like $300.
I still want to believe that few were yet to cashout due to one reasons or the other but just as you've said, how amazing would this have turn to when they got to discover what's in for them in the wallet, by then the whole world could have seen what they all termed "stupidity" act of Nayib Bukele turn to wealth and fame.
In my opinion, Bitcoin adoption in El Salvador has failed, because government was boosting adoption and infrastructure wasnt ready for Bitcoin.
What infrastructure? what else could El-Savador have developed more than all it has, btc ATMs, mining rigs, bitcoin city/beach, bitcoin tourist centre, chivo wallet for all citizens with free $30 worth bitcoin, good accessible network frame and regulations suitable enough unlike India demanding 30% on tax, many institutions, organizations and companies all accept cryptocurrency for transaction in the country, then what else could Bukele have done? The president just set a good example and never forced anyone to use it, should we still blame him for that.
