Economists judge a store of value against a specific checklist: it should be scarce, durable, divisible, portable, fungible, and hard to counterfeit or confiscate. Gold has passed that test for millennia because its supply grows only slowly through mining, it never corrodes, and it can be melted into any size. Fiat currencies fail the scarcity test since central banks can expand the money supply, which is why cash steadily loses purchasing power to inflation and rarely functions as a long-term store of wealth on its own.

Bitcoin is built to mimic gold's scarcity in digital form. Its protocol caps total issuance at 21 million coins, releases new supply on a fixed schedule that halves roughly every four years, and cannot be altered without overwhelming network consensus. Because it is purely digital, it is also easier to transport, divide into tiny fractions, and secure than a bar of metal, which is why proponents call it "digital gold."

Traditional stores of value: gold, silver, land, fine art
Digital stores of value: Bitcoin, and to a lesser extent other large-cap assets with fixed or predictably declining issuance

The unresolved question is whether Bitcoin's price behavior actually matches the role. Its annualized volatility has historically run several times higher than gold's, and it often trades in step with risk assets like technology stocks rather than acting as a safe haven during market stress. This distinguishes it sharply from a stablecoin, which sacrifices any upside to hold a fixed price instead. Whether an asset can serve as both a store of value and a medium of exchange remains a separate, actively debated question.
