Lesson 1: How Can Bitcoin Be Worth Anything?

— Value is subjective and emerges from the relationship between a good and a human need, not from properties embedded in the thing itself.

— Scarcity is a permanent condition of the human condition—people always want more than they can have, forcing them to make choices.

— An economic good must be both useful and scarce; usefulness alone (like air) or scarcity alone (like a unique rock) does not create economic value.

— Prices emerge at the margin from millions of individual subjective valuations and trades, not from any central authority.

— Every voluntary trade has two winners; both parties believe they are trading something less valuable for something more valuable to them.

— Bitcoin derives value because it is useful to people (fixed supply, self-custody, no censorship, verifiable rules) and scarce, creating demand that cannot be satisfied by simply creating more.

— Evaluate your own money choices at the margin: when deciding where to allocate savings, compare Bitcoin against your realistic alternatives (cash, stocks, bonds, gold, real estate) based on what you actually need in the future, not abstract total value comparisons.

— Understand that Bitcoin's value depends entirely on whether it solves a problem for you; if you find its properties useful for saving, transacting, or evading financial control, demand exists and price follows scarcity.
