Really interesting about Bukele's blog post.
People talking about BTC falling since El Salvador bought are completely missing the point. It wasn't bought as an investment - it was bought to encourage adoption of the Chivo wallet and it has succeeded massively. At least 40% of the population that was previously unbanked now are connected to a global financial system.
Also if you are primarily using BTC as a medium of exchange (its original purpose) rather than a store of value then the ups and downs of the price don't matter.
People are receiving BTC from remittances and salaries and business revenue and spending the BTC quite quickly on expenses.
In a fully BTC economy the price vs dying fiat currencies is irrelevant.
