Economics
Bitcoin is capable of being the new base layer of our economy, which is why understanding economics is essential in understanding Bitcoin. Bitcoin’s monetary policy is aligned with the Austrian School of economic thought, which is why reading the works of Austrian’s such as Hayek, Hazlitt, Hoppe, Menger, Mises, Rothbard (and others) is recommended by those who take Bitcoin’s value proposition seriously.
Human Action, Mises’ magnum opus, is freely available as both an ebook and an audiobook.
