A coin’s price tells you what one unit costs; it does not tell you whether the cryptocurrency is small, cheap, or likely to grow. To compare market size, multiply price by a stated supply measure—usually circulating supply—and then look at future supply, liquidity, use, and risk. A low unit price alone is not evidence of greater upside.
What is the difference between coin price and market cap?
Coin price is the quoted value of one coin or token at a particular time and on a particular market or data provider. Circulating market capitalization is that price multiplied by the provider’s estimate of circulating supply. CoinMarketCap gives the formula as “Market Cap = Price X Circulating Supply” in its FAQ.

This means two assets can have very different unit prices but the same circulating market cap. The figures below are hypothetical arithmetic, not live prices or forecasts:
| Hypothetical asset | Price per unit | Circulating supply | Circulating market cap |
|---|---|---|---|
| Token A | $2 | 100 million | $200 million |
| Token B | $0.02 | 10 billion | $200 million |
Token B’s lower price does not make it a smaller asset in this comparison: it has many more circulating units. Nor does either $200 million figure mean that amount of cash was invested or that all units could be sold at the quoted price.
Does a low coin price mean it has more room to grow?
No. Unit price alone says little about potential growth. A token priced at a fraction of a dollar can have a larger market cap than one priced in thousands of dollars if far more units circulate. Comparing only coin prices ignores supply and can make assets of very different sizes look comparable.
For context, corporate market capitalization is typically the public market price per share multiplied by outstanding shares, according to Investor.gov’s market-capitalization definition. Crypto comparisons often substitute circulating token supply, but supply conventions and verification vary by provider. A token is not thereby a share in a company, and crypto market cap does not necessarily carry the same legal or economic meaning as corporate equity market cap.
Which supply number is used in a crypto market cap?
“Supply” can refer to several different counts. CoinMarketCap’s FAQ calls circulating supply its “best approximation of the number of coins that are circulating in the market and in the general public’s hands.” Its supply documentation distinguishes that estimate from total and maximum supply:
Recommended Free Tools
- Circulating supply: the provider’s estimate of units currently circulating. It is used in the common circulating market-cap calculation.
- Total supply: units currently in existence, generally excluding units verifiably burned. Locked units may still count.
- Maximum supply: an estimated lifetime ceiling where one is stated or can be estimated. Some assets have no defined maximum.
These are not interchangeable. Providers may assess documentation, liquidity, volume, and trading venues when verifying supply or deciding how to treat market capitalization. Treat a reported supply as a provider’s estimate with a methodology, not as a universally settled count.
What is fully diluted valuation (FDV)?
CoinMarketCap defines FDV as maximum supply multiplied by price. It is a supply-sensitive scenario metric, not current circulating market cap and not a guaranteed future value. Its market-cap methodology also distinguishes circulating market cap from unlocked market cap, minted market cap—which uses total supply—and FDV. The provider explains these categories in its market capitalization documentation.
When comparing FDV with circulating market cap, you are asking how much larger the valuation would be at the current price under the specified supply assumption. The arithmetic holds price constant; it does not predict that price, demand, or market conditions will remain constant as supply changes.
How to compare two cryptocurrencies more usefully
- Compare current size. Use price multiplied by circulating supply, and use the same provider and timestamp for both assets where possible. Record which supply measure the quoted figure uses.
- Check potential supply expansion. Compare circulating, total, and maximum supply where available, then review issuance schedules, token unlocks, and allocation concentration. A large gap can indicate potential future selling supply, but it does not prove holders will sell or establish the price impact.
- Put FDV beside circulating market cap. The difference helps show how much the valuation changes under the stated supply assumption. Read it as static arithmetic, not a target price.
- Consider liquidity and trading conditions. Market cap is not a pool of cash available to sell every token at the quoted price. Trading volume, liquidity, and venues matter to how prices and supply estimates are interpreted.
- Ask what creates demand and what could undermine it. Consider the token’s function, design, and risks rather than treating a low price or a large projected valuation as an investment case.
What market cap and FDV cannot tell you
Neither metric predicts returns. They are descriptive calculations that depend on price and a chosen supply measure; they do not establish future demand, liquidity, adoption, or the ability to sell at a displayed price. The SEC’s investor-education material notes that crypto assets vary substantially in design and risk, while its September 9, 2024 bulletin describes bitcoin and ether as highly speculative investments. Those cautions do not predict losses or apply identically to every token, but they are a reason not to treat a low unit price or high FDV as proof of upside.
