When evaluating potential cryptocurrency investments, savvy investors go beyond price charts and examine the underlying fundamentals of a project. While market trends and sentiment matter, core metrics like circulating supply play a crucial role in understanding a digital asset’s long-term value and market dynamics.
Circulating supply is one of the foundational concepts in crypto tokenomics. It helps investors assess scarcity, calculate market capitalization, and anticipate future price movements. This guide breaks down what circulating supply means, how it differs from other supply metrics, and why it matters for your investment strategy.
Understanding Circulating Supply in Cryptocurrency
Circulating supply refers to the number of coins or tokens that are currently available in the public market and can be freely traded. These tokens are held by investors, stored on exchanges, or used in decentralized applications. In simple terms, it’s the portion of a cryptocurrency that’s actively "in circulation" and accessible to users.
It’s important to note that some tokens within the circulating supply may be temporarily locked in smart contracts or private wallets. However, as long as they can eventually re-enter the market, they’re still counted. This distinguishes circulating supply from tokens that are permanently removed or not yet released.

The Three Types of Cryptocurrency Supply
To fully grasp circulating supply, it’s essential to understand how it relates to two other key metrics: total supply and max supply. Each offers a different perspective on a cryptocurrency’s availability.
- Circulating Supply: The number of tokens currently available for trading and use in the market.
- Total Supply: The total number of tokens that have been created, excluding those that have been burned (permanently destroyed). This figure does not include tokens that are yet to be released.
- Max Supply: The absolute maximum number of tokens that will ever exist for a given cryptocurrency. Once this cap is reached, no new tokens can be created.
These values vary across projects depending on their design. For example, some cryptocurrencies have a fixed max supply, while others are inflationary with no upper limit.
Real-World Examples of Supply Metrics
Let’s explore how these supply types function in actual cryptocurrencies.
Bitcoin (BTC): A Fixed Max Supply Model
Bitcoin has a max supply of 21 million coins, making it a deflationary asset by design. As of now, approximately 18.34 million BTC are in circulation. The remaining coins are gradually released through mining rewards—currently 6.25 BTC per block.
Since Bitcoin doesn’t burn tokens, its total supply and circulating supply are effectively the same. Over time, as more blocks are mined, the circulating supply will continue to grow until it reaches the 21 million cap—expected around the year 2140.
This predictable issuance model creates built-in scarcity, which many investors view as a key driver of Bitcoin’s long-term value.
Cardano (ADA): Managing Supply Through Burns
Cardano presents a different case. Its max supply is capped at 45 billion ADA, but not all tokens have been released yet. Currently, about 34.76 billion ADA are in circulation.
The total supply stands at roughly 35.66 billion, meaning that over 894 million ADA have been burned—permanently removed from circulation through protocol mechanisms. These burns reduce the overall supply over time, potentially increasing scarcity and supporting price growth if demand remains steady or increases.
This example illustrates how projects can actively manage their token economy through strategic burns and controlled releases.

Why Circulating Supply Matters
Unlike traditional assets backed by physical commodities or corporate earnings, most cryptocurrencies derive their value purely from supply and demand dynamics. With no intrinsic backing, scarcity becomes a powerful factor in determining price.
A lower circulating supply often leads to higher per-unit value—assuming demand exists. However, rarity alone isn’t enough; the asset must also offer utility, adoption, or strong community support to maintain interest.
Calculating Market Capitalization
One of the most practical uses of circulating supply is calculating market capitalization (market cap):
Market Cap = Circulating Supply × Current Price per Token
This metric allows investors to compare the relative size and valuation of different cryptocurrencies. For instance, even if Coin A has a higher price per unit than Coin B, Coin B might have a larger market cap due to a much greater circulating supply.
Bitcoin consistently ranks as the largest cryptocurrency by market cap, reflecting both its high price and substantial—but still growing—circulating supply.
Can Circulating Supply Change Over Time?
Yes—circulating supply is typically not fixed. It evolves based on network activity, emission schedules, and governance decisions.
Mining and Token Issuance
In proof-of-work (PoW) systems like Bitcoin, new coins enter circulation when miners validate blocks and receive block rewards. These newly minted coins increase the circulating supply until the max supply is reached.
Similarly, in proof-of-stake (PoS) networks, validators are rewarded with newly issued tokens, gradually expanding the circulating pool.

The Role of Halving Events
Bitcoin’s halving mechanism is designed to control inflation. Approximately every four years—or every 210,000 blocks—the block reward is cut in half. This slows down the rate at which new BTC enters circulation.
Historically, halvings have preceded significant price increases due to reduced selling pressure and heightened scarcity expectations. The next halving is expected to further tighten supply growth.
Token Burns: Reducing Supply Strategically
Some projects actively reduce their circulating supply through token burns. This involves sending tokens to an unrecoverable wallet address—often called a "burn address"—effectively removing them from circulation forever.
Burns can be scheduled (like Binance’s quarterly BNB burns) or triggered by network activity (e.g., Ethereum’s EIP-1559 fee-burning mechanism). By decreasing supply, burns aim to counteract inflation and support long-term value appreciation.
Key Takeaways for Investors
Understanding circulating supply gives you a clearer picture of a cryptocurrency’s economic model. Here’s what to watch for:
- Projects with low or decreasing circulating supply may become more valuable if demand rises.
- High circulating supply doesn’t necessarily mean low value—but it can limit price spikes unless demand grows proportionally.
- Always check whether a project has a max supply and whether it conducts regular burns.
- Use market cap—not just price—to assess a project’s true size and potential.
Frequently Asked Questions (FAQs)
Is high circulating supply good?
A high circulating supply can enhance liquidity, making it easier to buy and sell large amounts without drastic price swings. However, excessive supply without matching demand can suppress price growth due to lower perceived scarcity.
What is the difference between total supply and circulating supply?
Total supply includes all tokens created minus those burned. Circulating supply only counts tokens actively available in the market. Some tokens may be reserved, locked, or not yet released—even if they’re part of the total supply.
What happens when circulating supply reaches max supply?
Once circulating supply equals max supply, no new tokens can be created. This creates permanent scarcity, which often supports price appreciation over time—assuming ongoing demand and utility.
How do token burns affect circulating supply?
Token burns permanently remove coins from circulation, reducing the circulating supply. This can increase scarcity and potentially boost the token’s value if demand remains constant or grows.
Does Ethereum have a max supply?
No, Ethereum does not have a fixed max supply. Instead, its issuance is controlled through monetary policy updates like EIP-1559, which burns transaction fees to offset new token creation and manage inflation.
Why is circulating supply used instead of total supply for market cap?
Market cap reflects the current market value of tradable tokens. Since non-circulating tokens aren’t available for trading, using circulating supply provides a more accurate picture of real-world valuation and investor exposure.
