I don't think there are any countries that are truly free of a central bank, it just means they are controlled by someone else's.
Examples are:
Andorra - EUR
Kiribati - AUD
Marshall Islands - USD
Micronesia - USD
Monaco - EUR
Nauru - AUD
Palau - USD
Panama - USD
Tuvalu - AUD
I was just pointing out that some may be thinking a country without a central bank is somehow free, which is incorrect.
Yes. Bitcoin fixes thus. Central banks are s menace to society.
