Scarcity
Definition
Scarcity means something exists in limited supply. In economics, scarce goods tend to hold or increase in value over time because demand can grow while supply cannot. Bitcoin is scarce by design — its code enforces a maximum of 21 million coins.
Example
Bitcoin's scarcity comes from its hard cap of 21 million coins — no one can create more.
