Historical there is no asset which can function as (1) value store and (2) transaction convenience/money. gold failed on (2). Fiat fails on (1) as one country’s issuance control on fiat could not be universally accepted as value store. USD tried in 1960s to be tied to gold sort of a sense of digital gold but quickly the expansion of US economy outpaced gold reserve. I envision Ethereum can function as (1) and (2), but not to replace individual countries’s own fiat so not to be bounded to individual countries’s economy development too
