This comparision is empty because anything exchange into the same results with the same. in other words: nobody exachange dollar into dollar unless they are not sound-minded.

Fiat currency is at its best second degree KBC because other countries decide on accepting or rejecting US economical indicators by temporarily betting on their short term future and set currency exchange point for the next 24 hours or so. Nobody buys US dollar because american flag is pretty or english is second broadest language in the world or some other “pretty face” indicator, as currency exhange dollar versus everything for the last 25 years clearly shows USD strenghtening +500% and weakening even 50% all the time.

No, Feds do not decide on this beauty contest. May be suprise to you but only 20% of printed dollar remains in usa. 80% is being shipped out for all sorts of purposes such as balancing countries oil wallets (aka petrodolar) to aiding other countries ending on fact that many countries prefer intra-use of greenbacks to its own currency. So Feds at its best control pretty face of dollar on its local playground aka USA, but in reality they dont because again dollar strength comes from evonomical indicators, not from how much feds prints.
