Understanding circulating supply is essential for anyone navigating the world of cryptocurrency. It’s a foundational metric that influences price dynamics, market sentiment, and investment decisions. Unlike total or max supply, circulating supply reflects the real-time availability of coins in the open market—those actively being traded, held, or used across decentralized applications.
This guide breaks down everything you need to know about circulating supply, how it impacts crypto valuation, and why it matters to investors in 2025 and beyond.
Understanding Circulating Supply
Circulating supply refers to the number of cryptocurrency tokens currently available for public trading on exchanges and within the broader market. These are coins that can be bought, sold, or transferred without restrictions. If a token is locked, reserved, or held in long-term escrow by developers or institutions, it is not included in the circulating supply.
For example:
- Bitcoin (BTC) has a circulating supply of approximately 19 million (as of 2025), nearing its hard cap of 21 million.
- Ethereum (ETH) has a circulating supply around 121 million, though this number fluctuates slightly due to issuance and burning mechanisms.

How Circulating Supply Differs From Total and Max Supply
It's crucial to distinguish between three key supply metrics:
- Circulating Supply: Coins currently in public hands and tradeable.
- Total Supply: All coins that have been mined or issued, excluding those verifiably burned.
- Max Supply: The maximum number of coins that will ever exist (if capped).
Not all cryptocurrencies have a max supply. For instance, Dogecoin has no supply cap, meaning new coins are continuously introduced into circulation.
A high circulating supply relative to total supply often signals maturity and accessibility. When circulating supply approaches total supply, speculation about scarcity may increase—especially if the max supply is finite.
The Impact of Circulating Supply on Price
Supply and demand govern crypto prices just like any financial asset. Circulating supply plays a direct role in determining market capitalization, calculated as:
Market Cap = Current Price × Circulating Supply
A lower circulating supply with strong demand can drive prices up significantly—this is the principle behind "scarcity premium." Conversely, a high circulating supply with weak demand may suppress price growth.
Consider these scenarios:
- A new meme coin launches with only 10% of its total tokens in circulation. As community interest grows, limited availability fuels FOMO (fear of missing out), potentially spiking prices.
- A well-established coin like Bitcoin sees gradual increases in circulating supply through mining rewards—but at a predictable, decreasing rate due to halving events.

Can Circulating Supply Decrease?
Yes—though less common than increases, circulating supply can go down. This happens through:
- Token burning: Permanent removal of coins from circulation (e.g., Binance periodically burns BNB).
- Staking locks: Users stake tokens in DeFi protocols like ShibaSwap, temporarily removing them from active trade.
- Protocol mechanisms: Ethereum’s EIP-1559 burns transaction fees, slowly reducing net issuance.
For example, when users unstake SHIB tokens from ShibaSwap, those coins re-enter circulation—causing a temporary spike in circulating supply. The reverse occurs when more users stake, reducing available supply.
This dynamic balance shows that circulating supply isn’t static—it evolves with user behavior and protocol design.
What Happens When a Crypto Reaches Max Supply?
Once a cryptocurrency hits its maximum supply, no new coins can be created. Bitcoin will reach this milestone around the year 2140. At that point:
- Mining rewards cease.
- Miners rely solely on transaction fees.
- The asset becomes inherently deflationary if token burns occur or lost coins exceed new usage.
Historically, assets with fixed supplies tend to appreciate over time if demand persists. This scarcity model mirrors precious metals like gold and underpins Bitcoin’s “digital gold” narrative.
However, reaching max supply doesn’t guarantee price increases—sustained utility, adoption, and investor confidence remain critical.
Is Low Circulating Supply Good for Crypto?
A low circulating supply can be beneficial—but only when paired with rising demand. Scarcity alone doesn’t create value; it amplifies value when people want what’s scarce.
Examples:
- TAMA has a max supply of 2 billion and employs deflationary mechanics, positioning it among finite-supply cryptos like BTC, XRP, AVAX, and ADA.
- Yearn.Finance (YFI) launched with no pre-mine and an extremely limited token distribution—making it one of the rarest major crypto assets by circulating supply.
Yet, low supply without use cases leads to stagnation. A project might have only 1 million tokens in circulation but fail to gain traction due to poor adoption or lack of utility.
Cryptocurrencies With Unique Supply Models
| Notable Examples |
|---|
- Bitcoin (BTC): Fixed max supply of 21 million; ~19 million in circulation.
- Ethereum (ETH): No hard cap; supply adjusts via issuance and burn mechanisms.
- Dogecoin (DOGE): Infinite supply; designed for spending rather than hoarding.
- Shiba Inu (SHIB): Massive total supply (quadrillions), but large portions are locked or burned.
Dogecoin’s uncapped model stems from its origins as a playful alternative to Bitcoin. Developers intended it to encourage everyday transactions by avoiding scarcity-driven hoarding.
Frequently Asked Questions (FAQ)
What does 100% circulating supply mean?
It means all available tokens are already in public circulation—none remain locked, reserved, or unissued. This typically occurs when a project has fully released its token allocation.
Does circulating supply affect market cap?
Yes. Market capitalization uses circulating supply—not total or max supply—to assess a cryptocurrency’s current market value. This provides a more accurate reflection of tradable value.
Why did Shiba Inu’s circulating supply increase?
When users unstake SHIB from platforms like ShibaSwap, those tokens return to circulation. Increased unstaking activity causes temporary spikes in circulating supply.
Which crypto has the lowest circulating supply?
Bitcoin stands out due to its strict 21 million cap. Among newer projects, Yearn.Finance (YFI) has one of the smallest supplies—around 36,000 tokens—with no inflationary minting.
Is high circulating supply good or bad?
Neither inherently. A high circulating supply can indicate maturity and liquidity but may dilute price growth if demand doesn’t keep pace. Context matters—compare it with trading volume, utility, and investor interest.
Can a crypto run out of circulating supply?
No. Even when max supply is reached (like Bitcoin eventually will), existing coins continue to circulate unless lost or burned. Lost private keys effectively remove coins from access—but they still count as part of the circulating total unless provably burned.
Final Thoughts: Why Investors Should Monitor Circulating Supply
Circulating supply is more than just a number—it’s a window into market dynamics. By tracking how tokens move in and out of circulation, investors gain insights into staking trends, inflation rates, and potential price catalysts.
Whether evaluating Bitcoin’s path to 21 million or analyzing how DeFi staking affects token availability, understanding this metric empowers smarter decision-making.
