Each of these monetary innovations has been coupled with a unique technological story. But, more fundamentally, all are connected with a deep yearning for some kind of revolution in society. The cryptocurrencies are a statement of faith in a new community of entrepreneurial cosmopolitans who hold themselves above national governments, which are viewed as the drivers of a long train of inequality and war.
And, as in the past, the public’s fascination with cryptocurrencies is tied to a sort of mystery, like the mystery of the value of money itself, consisting in the new money’s connection to advanced science. Practically no one, outside of computer science departments, can explain how cryptocurrencies work. That mystery creates an aura of exclusivity, gives the new money glamour, and fills devotees with revolutionary zeal. None of this is new, and, as with past monetary innovations, a compelling story may not be enough.
