🦸 The Three Superpowers of Money

This story introduces Carl Menger’s foundational economic concept of "salability," which is the ease with which a good can be sold on the market. For a good to naturally emerge as money, it must be highly salable across three dimensions: time, space, and scale. Salability across time means the good is durable, won't rot, and holds its value well. Salability across space means it has a high value per unit of weight, making it easy to transport over distances. Salability across scale means it can be conveniently divided into smaller units or grouped into larger ones without losing its core value. Historically, the precious metals gold and silver best fulfilled these roles. Today, Bitcoin serves as the ultimate evolution of this concept. It acts as a digital bearer asset that is instantly transportable, strictly scarce, and highly divisible, as each Bitcoin can be sliced into 100 million tiny, perfect pieces called satoshis.
