Fiat currency

Fiat currency can be Sterling, Dolar, Euro or any other legal tender that the government has declared. The value of fiat currency solely depends on the stability of the government and the economy of countries in which it is used. Fiat currencies have their value only because everyone involved agreed on it. If people lose faith in fiat money, it becomes worthless.

Compound interest is the 8th wonder of the world.
