Episode notes
Bitcoin Is A Medium, Not Yet Money
- Bitcoin currently functions as a medium of exchange but not as money in Mises' sense because it isn't universally accepted by a community.
- A money must be a commonly accepted medium of exchange, not merely an instrument held for later trade.
Which Category Could Bitcoin Fit?
- Mises' taxonomy splits money into commodity, fiat, and credit money, and Bitcoin can't be credit money because it's not a claim on another asset.
- That leaves commodity or fiat as the logical classifications for Bitcoin if it becomes money.
Mises' Tech vs Legal Distinction
- Mises defines fiat money as objects made money by a legal characteristic rather than by technological qualities of the good.
- Commodity money derives value from its physical attributes while fiat money's distinction is legal designation.
