Some of us have read Bastiat (in French!), Mises, Hayek, Rothbart, Solerno, and other "heterodox" Austrian economists, and have a better understanding of how money arises and how central bank interference in monetary and credit markets creates the boom and bust business cycles.

Bitcoin, with its Austrian hard money roots, stands head and shoulders above the crazy scammy mess of all the centralized altcoins (or "crypto" if you lile) that you right to criticize. Please don't lump real technological and computer science innovation in with a the crypto rug-pulls.

Most of them watched some youtube video providing a conspiracy theory view on banking, "fiat" currencies and debt-as-money.

They think they have deep insights when saying "banks create money out of thin air", or "there is not enough money in the economy to pay down all debt". They also use the word "fiat" as if it's bad that a currency is backed by a government.

All the above are strong indication that there is something fundamental about the monetary system that someone fails to understand.

A lot of crypto has been bought because the buyer were under such illusions.

The use case is digital money that doesn't require banks.
