A store of value is the function of an asset that can be saved, retrieved and exchanged at a later date, and it can be predictably useful when retrieved. More generally, a store of value is anything that retains purchasing power into the future. It is interesting to note that by this very definition, modern day fiat money does not offer a store in value, as over time, the buying power of fiat money diminishes in value. Therefore, by definition, fiat money does not fit the 3 basic criteria defining ‘money’.
