These are not new developments, and diplomacy has always been war by other means, including using currency as a weapon of war against external and internal enemies. Currency has always been a system of control and has frequently been weaponised in the past, it has certainly always been a tool of the ruling class. To provide some examples - Executive Order 6102 confiscated gold, the government then revalued it. During the American civil war could counterfeited currency was used to undermine currency, in WW2 the Nazis did the same to Britain. https://opinionator.blogs.nytimes.com/2012/03/27/a-counterfeiting-conspiracy/ https://opinionator.blogs.nytimes.com/2012/03/27/a-counterfe... You have never owned your money, it is simply a promissory note from a national bank, and it has always been valued according to what the government thinks is appropriate. Even money made from precious metals was the same, and was changed or devalued at the rulers whim. The same holds for unregulated crypto currencies, but instead of a government you have a cartel of miners and a small governing body of developers and stakeholders.
