What Money Actually Is

Quick Recap

• Money exists to solve the problem of bartering — matching up trades directly is slow and unreliable.
• Money holds real value through trust, scarcity, and backing by an authority — not because of what it's printed on.
• Saving protects the money you have; investing puts it to work so it can grow, accepting some risk in exchange.
• Understanding this distinction is the foundation everything else in this course builds on.
