Comment Unbacked != Fiat (Score 1) 631
Fiat currency and backing are different things. All fiat currency is unbacked, but just because a currency is unbacked, doesn't make it fiat.
Backed currency relies on the physical properties of the universe to create scarcity (i.e. anything backed by a physical thing is inherently limited). Fiat currency relies on the authority of the state to create scarcity (i.e. only the state is allowed to print money). Cryptocurrencies like bitcoin rely on mathematical principles to create scarcity. Bitcoin is not backed; it's also not a fiat currency.
