What Is Money?

Before Bitcoin makes sense, money has to make sense. Learn the three jobs money performs and what makes some money better than others.

Lesson path

Short, guided, and hard to get lost in.

Imagine trading without prices or a common payment good. Every exchange depends on finding the perfect match.

Money helps as a medium of exchange, unit of account, and store of value.

Score bananas, dollars, gold, and Bitcoin against durability, portability, divisibility, scarcity, and acceptance.

Try it

A café lists espresso at $3 and a sandwich at $9. What job is money doing?

Reflect

Write one sentence explaining why society needs money.

Host mode version

Use candy, a real dollar, and a play-money bill. Let the group decide which one they would accept, then ask why.

Next action

Keep momentum. The app should always make the next step obvious.
