> Money, in other words, mostly measures trust. This is less obvious for precious metals or cryptocurrencies because they have an intrinsic value of their own as well Cryptocurrencies have intrinsic value? Did the author intent to write that or was it an accident? S/he has grouped precious metals, which have purposes from engineering to jewellery - with solutions to arbitrary cryptographic problems, which are useless…
Cryptocurrencies likely follow a similar model. Useless to the lay-person except as decoration. Representing a "colossal waste of resources", but having access to the refining tools / techniques also has some commercial value.
Is gold useless except for swindling? Was trading land for gold (or vice versa- gold for land?) was that swindling?
I'd love to hear your rebuttal.
