But what has occurred is that as far as the people are concerned they do not have any meaningful currency to rely on, as the paper that we use for our activities can be devalued at the drop of a hat
Crypto may have a place but it to does not have a set value, it can be manipulated at will by the big boys
In earlier days they had Salt, Shells and any number of types of currency which the ordinary people could rely on
Money is also just manipulated for the benefit of the banks and the politicians and if that means the people lose the lot --- so what
I think that a standard set by a "basket of currency" would be lots more stable, rather than the US dollar being the "standard"
