Gold meets the definition of a currency under the free market system, but since the end of the gold standard in 1971, governments are no longer allowed to peg their currency to gold. Some argue that gold is the only valid global currency, call it the other currency, as it is universally accepted as payment and has value, which fluctuates based on economic conditions and supply and demand. Therefore, gold is the only currency that is also a commodity, giving it more actual value than any government-circulated fiat currency.
