What Is Maximum Supply in Crypto?

Maximum supply is the upper limit on how many coins or tokens can ever exist. Bitcoin has a max supply of 21 million. Once that is mined, no new Bitcoin will be created. Not all cryptocurrencies have a cap. Ethereum, for example, has no fixed maximum; supply changes with issuance and burning.

Why It Matters

A fixed max supply can support the idea of scarcity: no one can "print" more. That can matter for store-of-value narratives. Inflationary supply (new coins over time) can reward validators or stakers but may dilute holders. Compare max supply with circulating supply to see how much is left to be released.

Reality

Max supply alone does not guarantee value. Demand matters. Some coins with a cap have failed; some without a cap have grown. Use it as one factor when researching, along with use case, distribution, and team.
