> Most normal currencies are the same as bitcoin/crypto in that they are mostly digital but at least they have some mostly agreed upon value within their system The Dollar has an agreed-upon value of 1 Dollar per Dollar, the Euro of 1 Euro per Euro and the Bitcoin of 1 Bitcoin per Bitcoin. There are no agreed-upon values in any currency in free market. In socialism, they would dictate that a pound of butter had to cost 1unit of some currency. But in capitalist free markets, the value of a currency is always measured realtive to others things, being it goods (such as a standardized shopping baskets used for CPI) or other currencies or assets. For example, there is no way to determine if the dollar raised or fell - it always has a value of one dollar. But there is the DXY ("dixie") dollar index, where the value of the dollar is measured by its trading price with a basket of other currencies. Now if the DXY falls, you can say the dollar lost value. You could also say, the foreign currencies increased in value. It is always relative. Plus, 100 dollars bought a whole lot of things 50 years ago, a lot less things 30 years ago, and today the same 100$ buy a lot less than that. There is no agreed upon value, it is supply and demand.
