What is Circulating Supply? Complete Guide
Circulating supply is the number of cryptocurrency tokens publicly available and actively trading in the market, excluding locked or reserved tokens.
What is Circulating Supply?
Circulating supply is the number of cryptocurrency tokens or coins that are publicly available and actively trading in the market at a given moment. It excludes tokens that are locked, reserved, vesting, or otherwise unavailable for trade — such as team allocations under cliff, treasury reserves, or staked tokens with long unbonding periods.
Circulating supply is one of the most important metrics in crypto valuation because it directly feeds into market capitalization calculations: market cap = price × circulating supply. Two tokens with identical prices but very different circulating supplies have vastly different valuations.
How Does It Work?
Circulating supply differs from two related metrics:
- Total supply: All tokens that have been minted, including locked or staked. - Max supply: The maximum tokens that will ever exist (e.g., Bitcoin's 21 million).
Circulating supply changes over time as new tokens are issued (through mining, staking rewards, or vesting unlocks) and as tokens are burned or destroyed. Bitcoin's circulating supply grows by roughly 450 BTC per day post-2024 halving, while Ethereum's can be net-deflationary depending on burn rates relative to issuance.
Aggregators like CoinGecko and CoinMarketCap track circulating supply for thousands of tokens, with methodology guidelines requiring exclusion of unequivocally locked tokens.
History and Evolution
The concept gained prominence as the ICO boom of 2017-2018 produced thousands of tokens with complex vesting schedules. Investors learned painfully that comparing tokens by price alone was misleading: a $1 token with 10 billion circulating supply has 10x the market cap of a $1 token with 1 billion circulating supply.
The 2021-2025 era introduced more sophisticated tokenomics — locked allocations, retroactive vesting, programmatic burns, and dynamic emission schedules. Aggregators tightened their definitions, and "fully diluted valuation" (FDV) became a popular companion metric to flag potential future supply unlocks.
Key Concepts
- Token unlocks: Scheduled releases of vested tokens that increase circulating supply. - Token burns: Permanent removal from supply, reducing circulating amount. - FDV (Fully Diluted Valuation): Price × max supply — useful for projecting future dilution. - Inflation rate: Annual percentage increase in circulating supply.
Practical Example
Consider a new Layer 1 token, "ChainX," priced at $5 with a max supply of 1 billion. At launch, only 100 million tokens (10%) are circulating — held by early users from an airdrop. The market cap is $500 million, but the fully diluted valuation is $5 billion. Over the next two years, team and investor tokens unlock at 5% per quarter. If demand stays flat while supply doubles, the price could halve. Smart investors track unlock schedules to anticipate this dilution pressure.
Related Terms and Next Steps
Circulating supply is most useful alongside market capitalization, broader tokenomics analysis, and supply schedules driven by events like Bitcoin's halving.
