What if the government of a country is irresponsible and issues a large amount of currency to buy Bitcoin?
I don't see this as being irresponsible. El Salvador has added bitcoins to their balance sheet for a couple of years now and other countries doing so would only make Bitcoin more popular among their citizens and grow adoption.
I don't believe the case of El Salvador is valid to the point OP is trying to make. I believe OP is talking about a government led my crooks who would ruin the national economy in order to get Bitcoin for their own selfish purposes. That is that I understood, I guess.
As far as I know, El Salvador uses USD (American dollars) as official currency within her territory, so realistically El Salvador cannot print more FIAT., for obvious reasons.
