At the moment I actually have doubts about the banknotes we always use for buying and selling. why a piece of paper has such a high value. ??
When compared with gold, obviously gold would be more suitable to be a currency because gold has an instrinstik value and is also a precious metal. while paper money has no instrinsthetic value and is also not a precious metal like gold.
Paper money can not be eaten, if compared with food to eat food will be more valuable than paper money.
money is also controlled by a state-owned entity, such as a central bank and also has exchange rates in various countries, thus harming a country with a low exchange rate.
Paper money itself is as valuable as the paper we wipe our ass on. It's not backed up by gold as it used to be, once upon a time a bank note was an IOU for a small chunk of silver or gold held at the bank. I think crypto will be as useless as paper money in the future.
maybe that also can happen, depending on the state of the future
