Circulating supply is one of the first numbers investors should check, yet it is often ignored in favor of price. A token’s price tag says very little on its own. What matters is how many coins or tokens are actually available in the market, because that is what gives context to valuation, market cap, and dilution risk.
What circulating supply actually measures
Circulating supply refers to the number of coins or tokens currently available to the public. These are the units that can be traded, transferred, spent, or held in wallets. It excludes tokens locked by vesting schedules, coins that have been burned, and reserves that a project has not released.
The article compares this to money in the real economy. A project may advertise a very large total supply, but only a fraction of that amount may be live in the market. Bitcoin is a clear example: its maximum supply is fixed at 21 million, while about 19.7 million BTC were in circulation as of May 2025. The remainder has either not been mined yet or has effectively disappeared in lost wallets.
The basic formula is simple, but the details matter
A standard way to calculate circulating supply is total supply minus locked tokens minus burned tokens. In practice, this means removing coins held in team wallets under vesting, tokens reserved for staking rewards or development, and coins permanently destroyed by sending them to inaccessible addresses.
The source gives a straightforward example. If a project has 1 billion tokens in total, with 200 million locked for the team and 100 million already burned, then the circulating supply is 700 million. Some networks are less static. Ethereum, for instance, can see supply move in both directions because EIP-1559 burns part of the ETH used in transactions.
Investors usually track these numbers through tokenomics documents, blockchain explorers such as Etherscan, and data platforms like CoinGecko and CoinMarketCap. Still, the source warns that figures can be stale or incomplete, especially when a project does not clearly disclose unlock schedules or burn activity.
Centralized and decentralized projects do not handle supply the same way
Supply structure depends heavily on who controls distribution. In centralized projects, a small group may control a large share of tokens, with substantial amounts held back and released over time. That can leave the visible circulating supply lower than the amount that may later reach the market. The source points to XRP as an example, noting that Ripple Labs holds a large share and releases it gradually.
Decentralized projects follow issuance rules built into code. Bitcoin fits that model: new coins enter circulation through mining at a fixed pace, and no single party can suddenly accelerate issuance. For market participants, the question is not only how much is circulating now, but also who controls what comes next.
Circulating, total, and maximum supply each answer a different question
These terms are often mixed together, though they describe different layers of a token’s economy. Circulating supply covers the tokens already active in the market. Total supply includes all tokens that currently exist, including those locked, reserved, or staked, while excluding coins that have been permanently burned. Maximum supply is the hard ceiling on how many tokens will ever exist, if such a ceiling exists at all.
Bitcoin has a 21 million cap. Ethereum does not have a fixed maximum supply. Looking at only one of these figures can distort the picture. Circulating supply shows what is liquid today; total and maximum supply help reveal future issuance and long-term dilution risk.
Why supply can move prices sharply
A low token price can look attractive, but if circulating supply is already very large, the market cap may also be large. That leaves less room for the valuation story some traders assume from the unit price alone. On the other side, a low circulating float can send prices higher very quickly when demand rises, though it can also make moves more violent because liquidity is thinner.
The source highlights two unlock-driven examples. After a large Aptos token unlock in October 2024, APT fell more than 12% in a single day. In another case, about 40 million Trump meme coin tokens worth roughly $300 million entered the market in April 2025. The token price dipped, extending its decline to 90% from the all-time high.
Market capitalization starts with circulating supply
Market cap is typically calculated as price multiplied by circulating supply. It reflects the market value assigned to the tokens already in circulation at current prices. That is useful, but incomplete. It does not include the potential impact of large amounts of locked or reserved tokens that may unlock later.
A token can appear to have a modest market cap simply because only a small share of its total supply is live. If a large tranche is scheduled for release, that valuation picture can change very fast. Circulating supply helps judge present value; total and maximum supply are needed to assess future pressure.
How investors can use the metric
The practical takeaway from the source is direct: check how much of a token is already circulating, how much remains locked, and when new supply is expected to hit the market. A small float can support upside in the short term, but it can also set up a dilution event once vesting cliffs or incentive emissions begin.
Projects with limited supply, such as Bitcoin, are often compared with digital gold because scarcity is central to their value case. Others may intentionally use large supplies to support micropayments or broad distribution. A high supply count is not automatically negative. What matters is issuance speed, token use, and whether demand can absorb incoming supply.
Tools such as CoinGecko, CoinMarketCap, and TokenUnlocks can help compare current supply, maximum supply, and release schedules. In crypto markets, circulating supply is not a background statistic. It sits near the center of price formation.
