Circulating Supply vs Total Supply vs Max Supply

When evaluating a cryptocurrency, three supply numbers often appear side by side: circulating supply, total supply, and max supply. Mixing them up leads to bad decisions — especially about market cap and future dilution.

The Three Definitions

• Circulating supply is the number of tokens currently available and trading in the market. This is what market cap is based on.
• Total supply includes all tokens that exist — circulating plus any that are locked, vested, or reserved but already minted.
• Max supply is the maximum number of tokens that will ever exist. Some coins (Bitcoin) have a hard cap; others (Ethereum, Dogecoin) do not.

Why the Difference Matters

Market cap = price × circulating supply. But if a project has a small circulating supply and a huge max supply, most tokens are not yet in the market. When they unlock, they can create selling pressure. This gap is captured by fully diluted valuation (FDV).

A Simple Example

• Token X trades at $1.
• Circulating supply: 100 million → market cap = $100 million.
• Max supply: 1 billion → FDV = $1 billion.
• 900 million tokens (90%) are not yet circulating. When they unlock, supply could rise sharply.

Common Misunderstanding

A low token price does not mean a project is "cheap." A $0.01 token with a 10 trillion max supply has a much larger FDV than a $50,000 token with a 21 million cap. Always compare supply, not just price.
