The more the public learns about crypto, the stupider the coverage gets. It's like watching a kitten in a fuckin' paper bag.
This leads to another big challenge: data. Whether run by a governing board or software, the currency would need constant information on employment, wage growth, inflation, incomes, and more from among its users. Otherwise supply wouldn't properly adjust to need. This would probably require some sort of human-run bureaucracy: our hypothetical cryptocurrency's non-governmental equivalent to the U.S. Bureaus of Labor Statistics and Economic Analysis. Conceivably, you could try to build that information into the blockchain codes instead, but I have no idea whether it's feasible.
fuckin' cargo cult economics up in this bitch.
