Understanding the fundamentals of cryptocurrency metrics is essential for any investor or enthusiast navigating the digital asset space. One of the most critical yet often misunderstood concepts is circulating supply. This metric plays a central role in evaluating a cryptocurrency’s market value, scarcity, and long-term potential.
In this comprehensive guide, we’ll break down what circulating supply means, how it differs from total and maximum supply, and why it matters when analyzing crypto assets.
What Does Supply Mean in Cryptocurrency?
In the world of digital currencies, "supply" refers to the number of coins or tokens that exist for a particular cryptocurrency. However, not all supply metrics are the same. There are three primary types:
- Circulating Supply
- Total Supply
- Maximum Supply
Each offers unique insights into a token’s availability, inflationary behavior, and economic model.

Circulating Supply: The Coins Available Today
Circulating supply is the number of coins currently available for trading in the open market. These are the tokens held by investors, stored in wallets, or actively being bought and sold on exchanges.
It’s important to note that circulating supply does not include:
- Coins locked in escrow
- Tokens reserved for team members or early investors
- Staked tokens temporarily removed from circulation
- Coins held in reserve by the project
Because only freely tradable coins affect market dynamics, circulating supply is used to calculate market capitalization, not total or maximum supply.
As Sudhir from The Money Mongers explains, “Circulating supply is not the same as total supply or maximum supply. One can own some of the tokens and keep it away from the market. As a result, those coins will not be part of the circulating supply.”
This distinction is crucial—just because a project has issued millions of tokens doesn’t mean they’re all influencing price action.
Total Supply: All Coins That Exist
Total supply includes all coins that have been created so far, minus any that have been verifiably burned (destroyed). It encompasses both circulating tokens and those locked up or reserved.
For example:
- If a project has 80 million tokens in circulation and 20 million locked for team vesting, with no burns, the total supply is 100 million.
- If 5 million tokens are later burned, the total supply becomes 95 million.
Unlike circulating supply, total supply can change over time—increasing with new minting or decreasing through token burns.
Maximum Supply: The Hard Cap
Maximum supply, also known as fixed supply, represents the upper limit of how many coins will ever exist for a given cryptocurrency. Once this cap is reached, no more tokens can be created.
Bitcoin is the most famous example: its maximum supply is capped at 21 million coins. This hard cap is coded into Bitcoin’s protocol and enforced by consensus, making it inherently deflationary over time.
Other projects may have different models:
- Ethereum does not have a fixed maximum supply (though issuance is controlled).
- BNB originally had a max supply of 200 million but reduced it via quarterly burns.
A fixed maximum supply helps combat inflation and increases perceived scarcity—key drivers of long-term value.
Key Differences: Circulating vs. Total vs. Maximum Supply
| Concept | Definition | Used For |
|---|---|---|
| Circulating Supply | Coins actively traded in the market | Market cap calculation, liquidity analysis |
| Total Supply | All issued coins minus burned ones | Project transparency, tokenomics evaluation |
| Maximum Supply | The absolute ceiling on coin creation | Scarcity assessment, investment decision-making |
While tables aren’t allowed in final output, this conceptual breakdown highlights why understanding each term matters.

How to Calculate Circulating Supply
There is no universal formula for calculating circulating supply because it depends on how each blockchain defines "available" tokens. However, the general principle is:
Circulating Supply = Total Issued Tokens – Locked, Reserved, or Inactive Tokens
For example:
- A new DeFi token launches with 100 million total tokens.
- 40 million are locked for development and ecosystem incentives.
- 5 million are burned during launch.
- The remaining 55 million are distributed to public investors and listed on exchanges.
Thus, the initial circulating supply is 55 million.
Over time, as locked tokens unlock (e.g., after vesting periods), the circulating supply increases—potentially affecting price due to increased selling pressure.
Some projects intentionally reduce circulating supply through token burns, where coins are sent to an unrecoverable address. This permanently removes them from circulation, increasing scarcity.
BNB’s quarterly burn program is a prime example. Binance commits to burning a portion of its profits in BNB until 100 million tokens are destroyed—halving its original max supply.
Why Circulating Supply Matters: Market Capitalization
Market capitalization (market cap) is one of the most widely used indicators of a cryptocurrency’s size and stability. It’s calculated using:
Market Cap = Current Price × Circulating Supply
Let’s say:
- A token trades at $10
- Its circulating supply is 5 million
Then:
- Market Cap = $10 × 5,000,000 = **$50 million**
This figure helps investors compare projects regardless of price alone. A $1 coin with a high circulating supply might have a larger market cap than a $100 coin with very few tokens available.
Platforms like CoinMarketCap and OKX provide real-time tracking of these metrics so you don’t have to calculate manually.
What Happens When Circulating Supply Reaches Maximum Supply?
When a cryptocurrency hits its maximum supply:
- No new coins will be mined or minted
- Miners or validators are rewarded solely through transaction fees
- The asset becomes fully deflationary (if burns continue)
Bitcoin will eventually reach this state—estimated around the year 2140. At that point:
- Transaction fees will become the primary incentive for miners
- Network security will rely on user-paid fees rather than block rewards
- Scarcity could drive increased demand
Historically, halving events (which reduce mining rewards) have preceded major price surges. A fully exhausted supply may amplify this effect.
Frequently Asked Questions (FAQ)
Q: Can circulating supply decrease?
Yes. Through mechanisms like token burns or extended lock-up periods, circulating supply can shrink. For example, Binance burns BNB quarterly, reducing available tokens and potentially increasing value.
Q: Why isn't total supply used for market cap?
Because only coins available for trading influence price. Including locked or reserved tokens would distort valuations and mislead investors.
Q: Is a low circulating supply good?
Not necessarily. A low number might suggest scarcity, but it could also mean limited liquidity or centralization risk if most tokens are held by insiders.
Q: How often does circulating supply change?
It varies. Bitcoin’s increases roughly every 10 minutes with new blocks. Others change during unlock events or burns—sometimes quarterly or annually.
Q: Where can I check a coin’s circulating supply?
Reliable sources include OKX, CoinGecko, and CoinMarketCap. Always verify data across platforms for accuracy.
Q: Does staking affect circulating supply?
Technically no—staked coins are still counted as circulating unless officially removed from circulation by protocol rules.

Final Thoughts
Understanding circulating supply is foundational to smart crypto investing. It influences market cap, liquidity, volatility, and long-term value potential. By distinguishing it from total and maximum supply, you gain deeper insight into a project’s tokenomics and economic design.
Whether you're evaluating Bitcoin’s scarcity model or tracking BNB’s burn schedule, always consider how much of a token is truly available in the market—and how that might change over time.
Stay informed, track reliable data sources, and make decisions based on transparent metrics.
