A quick history of currencies and paper money shows that money began as a deposit of a certain value of gold/silver and then turned into a representation of the promises of those who issue it.
Looking at the US dollar, it has lost more than 90% of its value, making all paper currencies a bad example of a "store of value." "I do not want to mention the scenario that happened in the state of Venezuela or Germany after the war."sagame
Fiat currencies could never be considered store of value because their value is decreasing. If someone will hide a big amount of fiat under the ground to make sure he has something to spend after a decade or so, he will most probably have so little to buy with that same amount by the time he digs it up. The problem with fiat is that it is not valuable in itself unlike gold or even Bitcoin to a certain extent. Fiat is just a piece of paper without value.
