Lol! I don't agree that the euro would've been a better option given the current situation.
If they were to choose the euro or us dollar, then they would be at the whim of their respective central banks. The european central bank could print lots of euro and crash the euros price, in essence they would be under their control if they did that. The only way a nation like liberland could remain free would need to have its own currency or use one that isn't issued by a central authority.
Euro is complete shit and that has been proved on a national level. The US dollar is already controlled by a central authority and using centralized currency would get them to stay on a leash. Bitcoin as a national currency could be the best possible decision but Satoshi as prime minister is a rumor hahaha.
Despite the eurozone scandal, I wouldn't call it complete shit, but yes it is barely nothing in comparison of bitcoin. As the country is small in size, it is wise for them to choose the bitcoin currency. The adoption and trade in market also increase due to this. ALTHOUGH, Satoshi as Prime minister? HAHAHAHA. Oh god, where do you guys all this kind of fake rumors?!
If I were Liberland I would allow the use of Bitcoin for import export but also create my own parallel digital currency with a finite amount of coins which would really boost the economy because being a digital currency of one country it would enable locals to be encouraged to save more which would drive up the price as well.
