A coin’s price tells you what one unit costs; its market capitalization estimates the value of all units counted as circulating. A token priced at $0.02 can have the same—or a larger—market cap than one priced at $2 if many more units circulate. So a low coin price alone does not show that an asset is cheap, undervalued, or more likely to grow.
What coin price and market cap measure
Coin price: the value of one unit
A cryptocurrency’s quoted price is the value of one coin or token at a particular time and on a particular market or data provider. It is a per-unit figure, not a measure of how large a project is.
Market capitalization: price multiplied by a supply measure
CoinMarketCap states the common circulating-market-cap formula as “Market Cap = Price X Circulating Supply.” In practice, the result depends on the provider’s estimate of circulating supply and the price it uses. It is an estimate of aggregate value at the quoted price—not cash invested in the asset, cash available to sell every token, or a forecast of what holders could receive.
For comparison, corporate market capitalization is generally the current public share price multiplied by outstanding shares, according to Investor.gov. Crypto commonly substitutes circulating token supply, but its supply definitions and verification are provider-specific; a token is not thereby a share in a company.

Why a low coin price does not mean more room to grow
Unit prices are meaningful only alongside the number of units in circulation. Consider this hypothetical arithmetic:
| Hypothetical asset | Circulating units | Price per unit | Circulating market cap |
|---|---|---|---|
| Token A | 100 million | $2 | $200 million |
| Token B | 10 billion | $0.02 | $200 million |
Both examples have the same circulating market cap despite a 100-fold difference in unit price. The arithmetic does not say either token is a good investment, that $200 million has been invested, or that either will rise. A hypothetical move from $0.02 to $2 would also require assessing the resulting valuation and supply—not simply noting that the price reached a round number.
Which supply number is being used?
Supply measures describe different things, so a market-cap-like figure is only clear when its supply basis is named. CoinMarketCap’s FAQ calls circulating supply “the best approximation of the number of coins that are circulating in the market and in the general public’s hands.” Its terminology is a provider’s methodology, not a universal guarantee that every unit is freely tradable.
- Circulating supply: the provider’s estimate of units circulating in the market and public hands. Circulating market cap is price multiplied by this estimate.
- Total supply: units currently in existence, generally excluding units that can be verifiably shown to have been burned. Locked units may still count.
- Maximum supply: the estimated lifetime ceiling when one is stated or can be estimated. Some assets have no defined maximum supply.
CoinMarketCap’s supply documentation also explains that verification can consider project documentation, liquidity, volume, and trading venues. Supply figures are therefore estimates with methodology behind them; different providers may report different values or use different labels.

How to interpret FDV and other market-cap figures
Fully diluted valuation (FDV) is not the same as current circulating market cap. CoinMarketCap defines FDV as maximum supply multiplied by price. It is a static calculation at the current price under a specified maximum-supply assumption—not a guaranteed future valuation or a target price.
CoinMarketCap also distinguishes circulating market cap from unlocked market cap and minted market cap. Its market-capitalization methodology describes measures based on circulating, unlocked circulating, and total supply, as well as FDV based on maximum supply. When reading a ranking or valuation, check the label and underlying supply measure rather than treating every figure called “market cap” as interchangeable.
A large gap between circulating market cap and FDV can indicate that substantial supply is not yet included in the circulating figure. It does not establish that those units will be sold, when they may enter circulation, or what effect any release would have on price.
A practical framework for comparing two cryptocurrencies
- Compare current size on a consistent basis. Use the same provider and a similar timestamp where possible. Calculate or check price multiplied by circulating supply, and make sure both figures use circulating supply rather than mixing in FDV or another measure.
- Check potential supply expansion. Compare circulating supply with total and maximum supply, then review issuance schedules, unlocks, and allocation concentration. A large gap can mean potential future selling supply, but it does not prove holders will sell or predict the price impact.
- Put FDV beside circulating market cap. The difference shows how much larger the valuation would be at the current price under the stated supply assumption. Treat it as arithmetic, not as a price target or prediction.
- Consider liquidity and trading conditions. Volume, liquidity, and the venues on which an asset trades affect how useful a quoted price is in practice. Market cap does not mean all tokens could be sold at that price; CoinMarketCap also considers liquidity, volume, and trading venues in supply verification.
- Ask what could create demand—and what could undermine it. Consider the token’s function, the conditions for its use, and risks specific to its design and market. A valuation metric cannot substitute for that assessment.
What these metrics can—and cannot—tell you about growth
Price, circulating market cap, supply schedules, FDV, and liquidity help describe an asset’s current scale and supply conditions. They do not establish that it is undervalued or estimate the return it will deliver. A larger market cap is not automatically safer, and a smaller one is not automatically more promising.

Investor.gov notes that crypto assets differ significantly in characteristics, design, and risks. In a September 9, 2024 bulletin about exchange-traded products providing exposure to bitcoin and ether, the SEC’s Office of Investor Education and Advocacy described those assets as highly speculative investments. That warning is specific to bitcoin and ether exposure; it is not a prediction about every token. For any crypto asset, uncertainty and risk matter alongside the arithmetic.
