The Holy Grail of Crypto Currencies: Ready to Replace Fiat Money?

This article suggests that current forms of crypto currencies will fail to complement or replace fiat money. We show that fixed-supply coins like bitcoin suffer from an inherently speculative and deflationary design and are not backed by a "We Owe You". Stablecoins, i.e. coins that rely on flexible supply designs, are also not backed by a "We Owe You" and cannot achieve price stability because they build on outdated monetarist theories. Moreover, the algorithmically planned allocation of new coins, which is characteristic of stablecoins, is not market-based. As such, it is inferior to contemporary ways of money creation. Regarding price stability, we suggest that (crypto) monetary policy needs to overcome the illusionary dichotomy between the real and the financial circuit by accounting for systematic coordinated wage bargaining mechanisms to reflect that firms set prices according to cost-based pricing rules.
