Having fiat currency "backed" by anything, like gold or silver, is meaningless. 1943 (?) proved this as the US, or any gov't, can simply reprice the value of the fiat relative to the backing asset.

The real value was when the asset (the money) itself was used as currency.

This is an important fact of bitcoin's value that is often misunderstood. Bitcoin IS the asset.

That said, #Litecoin #Monero & #BitcoinCash are also the asset, and a currency.
