A token can trade at $0.02 and still be overpriced. Another can trade at $2,000 and still have meaningful upside. Unit price is a weak signal in crypto because supply designs vary widely. Market cap corrects that bias by forcing a clearer question: what is the entire circulating network worth at today’s price?
Market cap (market capitalization) estimates the current market value of a crypto asset. It helps investors compare assets on a like-for-like basis, interpret price in context, and avoid the most common mistake in crypto valuation: treating a low unit price as “cheap.”
What is Market Cap?
In crypto, market cap = current price × circulating supply.
For example, if a token trades at $2 and has 500,000,000 tokens in circulation:
$2 × 500,000,000 = $1,000,000,000 → a $1B market cap
Market cap helps you answer practical questions fast:
- “How big is this asset compared to others?”- A $50B asset typically behaves differently from a $50M one.
- “How hard is it for this price to double?”– Doubling a $10M market cap often takes far less new demand than doubling a $10B one.
- “Does the upside story match the math?”– If someone says a token can “easily 50×,” market cap tells you what that implies in total valuation, not vibes.
Market cap uses circulating supply, not total supply, because circulating supply reflects tokens that can actually trade on the market right now.
Circulating supply typically includes:
- tokens held by the public and freely transferable
- tokens on exchanges and in wallets that can move without restrictions
Circulating supply often excludes or partially excludes:
- team/investor tokens under vesting schedules
- locked ecosystem or treasury allocations
- tokens reserved for future incentives
- tokens that exist in theory but aren’t released (or aren’t spendable yet)
This distinction matters because price discovery happens on the tradable float. If only a small portion of total supply trades today, the market can push price around more easily, then future unlocks can change the game by adding new supply that can be sold.
Circulating supply changes as projects:
- unlock tokens for teams/investors over time
- emit new tokens through staking rewards or mining
- burn tokens via fees or scheduled burns
- mint additional supply (if the design allows it)
When circulating supply rises faster than demand, market cap can stall even if the project keeps shipping because the market must absorb more sell pressure just to hold price steady.
Market cap is a price-based estimate, not a ledger of “money invested.” A token can jump 30% on relatively modest buying if liquidity is thin, and market cap rises with it. Market cap tells you what the market values the circulating supply at right now, not how much cash flowed in.
Circulating Supply VS Total Supply VS Max Supply
Supply terms describe what the market can price today versus what may enter circulation later. They appear frequently because they shape valuation, dilution risk, and long-term token economics.
| Term | What it means | What it includes | How it changes | Why it matters for investors |
| Circulating supply | Tokens available to the public and actively tradable (the “live float”) | Tokens that can move freely and trade on exchanges/DEXs | Can increase via emissions/staking rewards and unlocks; can decrease via burns or removals from circulation | This is the supply used for market cap, because it reflects the market’s real tradable supply and price discovery today |
| Total supply | Tokens that already exist on-chain (whether or not they can trade freely) | Circulating tokens plus tokens that may be locked, vested, or held in treasuries | Can rise through minting/emissions; can fall through burns | Useful for understanding how much supply exists in the system overall, but it can be a weak proxy for what the market can actually trade right now |
| Max supply | The ceiling: the maximum number of tokens that can ever exist (if enforced) | The upper limit set by protocol rules (if there is one) | Fixed if there’s a hard cap; some assets have no cap or flexible policy targets | Helps you gauge long-term dilution potential, especially when paired with emissions schedules and unlock mechanics |
CoinMarketCap prefers circulating supply for market cap because it’s closer to the public float concept in equities—the portion the market can actually trade today—so the valuation reflects current price discovery more accurately.
What is Fully Diluted Valuation (FDV)?
Market cap tells you what the market is valuing the tokens that are tradable today (circulating supply).
Fully Diluted Valuation or FDV zooms out and asks a different question: What would this project be worth if the full supply were already in the market at today’s price? That’s why people often call FDV a “future supply” version of market cap—it’s a dilution lens, not a promise.
FDV is typically calculated as: FDV = Price × Total supply or Price × Max supply, depending on how the project defines its final supply ceiling. Coinbase explains FDV as an estimate of market cap “when all tokens are in circulation,” and CoinMarketCap frames it the same way—multiply token price by total supply to estimate fully diluted value.
Looking at circulating market cap next to FDV helps you quantify dilution risk—how much additional supply could hit the market over time and compete with demand.
FDV helps people see the project “beyond the given point,” and it’s commonly used to sanity-check whether a token’s current valuation relies on a small circulating float.
A token can look “small” by market cap if only a small slice of supply is circulating—especially early in a project’s lifecycle.
But if a large portion of tokens sits locked for teams, investors, or treasuries, future unlocks can steadily increase circulating supply, which can create persistent sell pressure unless real demand grows fast enough to absorb it.
CoinMarketCap’s FDV explainers also highlight that FDV is useful for understanding tokenomics and the impact of supply coming into circulation over time.
Importance of Market Cap In Crypto
Market cap does not establish quality, but it improves decision quality in four consistent ways.
1. Market cap helps you compare “size” across tokens
Token price alone misleads because each project chooses a different supply structure. One token might have 10 million units, another might have 100 billion. A $1 token is not automatically “bigger” than a $0.01 token.
Market cap fixes that by giving you a shared yardstick. It lets you compare networks and categories on the same scale—L1s vs L2s, DeFi tokens vs gaming tokens, and so on—without getting tricked by unit bias.
2. Market cap acts as a rough proxy for liquidity and stability
Market cap often correlates with liquidity and stability, but it doesn’t guarantee either.
- Larger market caps often come with deeper order books, more market makers, more exchange listings, and more participants on both sides of the trade. That usually reduces slippage and makes price harder to push around with one big order.
- Smaller market caps often trade with thinner liquidity. A modest buy or sell can move prices sharply, which makes these tokens overshoot more easily in both directions. News, rumours, and sudden sentiment shifts also hit harder when the order book is shallow.
Treat market cap as a starting clue, then confirm with volume, order-book depth, and spread. A token can show a decent market cap on paper and still trade like an illiquid asset if real volume is thin or concentrated on one venue.
3. Market cap helps you spot dilution risk when paired with FDV
Market cap shows today’s valuation based on circulating supply. FDV estimates valuation when the full supply (total or max) circulates.
The gap between market cap and FDV helps you see a common setup: a token looks “small” today because only a small percentage of supply trades, while a large amount sits locked for teams, investors, or incentives.
As unlocks and emissions increase circulating supply, the market needs fresh demand just to keep prices stable. If demand doesn’t keep up, price often drifts down even if the project keeps building.
You don’t need FDV to be “low” for a token to work. You do need a supply story that makes sense: unlock schedules you can live with and demand drivers that can absorb new supply.
4. Market cap influences how investors classify risk
People often bucket crypto by market cap because it helps set expectations around volatility, slippage, and survivability
- Large-cap: more established, typically more liquid, usually less extreme moves
- Mid-cap: growth potential with higher volatility and more narrative-driven swings
- Small-cap: bigger upside stories, but higher manipulation risk, thinner liquidity, and harder exits
These buckets don’t guarantee safety. Large caps can still crash and small caps can still outperform. Market cap just helps you calibrate what “normal” looks like for that asset—how violent the swings might be and how easily you can get in and out without donating a chunk of your position to slippage.
How to Use Market Cap
Market cap works best as a first filter, not a final verdict. Use it to frame what you’re looking at, then pressure-test the token with a few follow-up checks so you don’t get trapped by thin liquidity or hidden dilution.
Compare market cap vs FDV to understand dilution risk.
Review both figures side by side. A wide gap typically indicates that a substantial portion of supply is not yet in circulation. This does not, by itself, invalidate the asset, but it does signal that future unlocks and emissions may create incremental sell pressure unless demand expands sufficiently to absorb additional supply.
If an asset’s market cap appears modest while its FDV is materially higher, the investment case implicitly assumes the market will eventually sustain today’s pricing across the full supply—an outcome that generally requires meaningful growth in utility and adoption.
Check circulating supply and upcoming unlocks (big cliffs matter).
Circulating supply reflects what the market can price and trade today; unlock schedules indicate how that tradable supply may expand over time. Review major vesting events, unlock dates, and incentive emissions that could increase available supply abruptly.
Unlock “cliffs” matter because they can shift the supply–demand balance quickly: even strong projects can underperform if a large wave of newly liquid tokens enters the market and early holders sell into available liquidity.
Pair market cap with 24h volume and order-book/DEX liquidity to estimate how easily you can exit.
Market cap is a valuation snapshot; it does not indicate how efficiently you can enter or exit a position. Trading volume and liquidity conditions provide that insight. An asset may display a sizable market cap yet still trade poorly if volume is thin, concentrated on a single venue, or supported by shallow order books or liquidity pools.
A practical discipline is to estimate price impact for your intended position size: if you would incur meaningful slippage under normal conditions—or particularly under stress—treat the asset as higher risk regardless of its market cap.
Sanity-check category peers (L1 vs L1, DEX vs DEX, gaming vs gaming).
Market cap comparisons only make sense inside the right bucket. Compare a Layer 1 to other Layer 1s, a DEX token to other DEX tokens, a gaming token to other gaming tokens. This keeps you from drawing the wrong conclusions from “rank” alone.
Once you’re comparing like-for-like, market cap becomes a useful reality check on narratives—whether a token already prices in huge adoption or still sits at a level that assumes modest growth.
