What market cap measures
Market capitalization estimates the value of circulating units at a quoted price. Use the same asset, supply definition and observation time. It is not the cash invested in the asset or the amount holders could collectively withdraw.
Market cap = price per unit × circulating units
Hypothetical USD example: a token priced at USD 2 with 3 million circulating units has a market cap of USD 6 million. These are illustrative values, not a live quote; all monetary examples on this page stay in US dollars.
A marginal trade can change the quoted price of every unit. Selling a large position can move that price, so market cap is not a measure of executable liquidity.
Market-cap groups are conventions
Large-cap, mid-cap and small-cap are relative labels. Providers use different cutoffs, currencies and asset universes, and classifications change with prices and supply. Compare groups only after reading the provider's rules and date.
A larger market cap does not guarantee deep order books, low volatility, reliable reserves or safety. A low unit price does not establish that a token is cheap: the number of units matters.
Supply and fully diluted valuation
Supply measures answer different questions. CoinGecko's methodology distinguishes the following quantities; other providers may classify locked or treasury holdings differently.
| Supply measure | Basis | What to check |
|---|---|---|
| Circulating supply | Units considered available to the public under the provider's methodology. | Locked, treasury and other excluded holdings; an unlocked token is not necessarily classified as circulating. |
| Total supply | Units already minted, minus units permanently burned. | Minting, burns and the observation time; non-circulating units can be included. |
| Maximum supply | The coded upper limit, if the asset has one. | Whether a finite limit exists and whether protocol rules can change it. |
Name the supply basis when quoting fully diluted valuation (FDV). CoinGecko calculates FDV from price × total supply. Some other presentations use maximum supply; these are different calculations when the two supplies differ.
Using the same hypothetical USD 2 token: 10 million total units give USD 20 million on a total-supply basis. A 12 million maximum gives USD 24 million on a maximum-supply basis. Neither is a price forecast.
A gap between market cap and FDV is not an unlock calendar. Check vesting schedules, minting rules, recipients and restrictions separately. Unlocking does not prove that tokens will be sold or establish the size of a future price move.
What volatility measures
Volatility describes price variability over a specified period. It does not say which direction the next move will take. A daily range, a standard deviation of returns and a peak-to-trough drawdown are different statistics.
Comparisons need the same return convention, sampling interval, window and annualization method. Annualizing a historical estimate does not turn it into a forecast or a worst-case loss bound.
Why price movements can accelerate
Thin order books, concentrated holdings, news, token supply changes and leveraged liquidations can amplify moves. Their effects depend on the asset, venue and market conditions. A plausible explanation after a move is not proof of causation or a reliable timing signal.
Many crypto markets trade around the clock, but venues can suspend markets or apply price bands and other controls. Binance's Price Range Execution Rule is one pair-dependent example. These mechanisms are not necessarily equivalent to stock-market circuit breakers, and availability can change.
Compare volatility measures
| Measure | What it describes | Interpretation limits |
|---|---|---|
| Realized volatility | Dispersion of observed returns over a chosen window, often expressed as an annualized percentage. | Results depend on the dataset, simple or log returns, sampling, window and annualization convention. Past dispersion is not a maximum future loss. |
| Implied volatility | An option-price-derived estimate under an index or pricing methodology. | Identify the provider, asset and horizon. Binance BVOL describes 30-day annualized implied volatility; no universal threshold proves that a trade is attractive. |
| Average true range (ATR) | An average of true ranges, measured in the price's units rather than a percentage. | Specify the number of periods and averaging method. Periods can be intraday, daily or longer; ATR does not predict direction. |
True range is the largest of: high minus low; the absolute difference between high and previous close; the absolute difference between low and previous close.
Hypothetical USD prices: high 101, low 99 and previous close 95 give candidate ranges 2, 6 and 4, so true range is USD 6. High minus low alone would miss the gap. ATR averages true ranges across the chosen periods.
What risk controls can and cannot do
Position size, leverage, collateral and executable order-book depth all affect loss exposure. Stop orders trigger an order; they do not guarantee the execution price. A stop-limit order may remain unfilled. Read the venue's liquidation and margin rules, including exposure from additional collateral.
Diversification can still leave correlated exposure. Regular fixed-amount purchases spread purchase timing, but do not guarantee profit or prevent large losses. Fees and the opportunity cost of holding cash also matter. No universal allocation, stop distance or reward/risk ratio is suitable for every person or market.
Read valuation and volatility together
| Observation | Useful question | Unsupported inference |
|---|---|---|
| Large market cap | How much can be traded on this venue near the quoted price? | That any position can be sold without slippage. |
| Low recent volatility | Which period was measured, and did liquidity or market conditions change? | That the next period will stay quiet or liquidation cannot occur. |
| FDV above market cap | Which supply basis is used, and what are the actual issuance and vesting rules? | That the difference will enter circulation immediately or be sold. |
Frequently asked questions
Does market cap show how much money was invested?
No. It multiplies a quoted unit price by circulating supply. It does not sum historical investment and does not show how much could be withdrawn by selling all units.
Is a token with a low unit price cheaper?
Unit price alone cannot establish relative valuation. Compare supply, market cap, supply rules and the rights or utility of the asset; none of these guarantees investment value.
Does FDV predict future selling pressure?
No. FDV values a specified supply at the current price. It does not identify unlock dates, holders' selling decisions or the future price. State whether the calculation uses total or maximum supply.
Is ATR the same as daily high minus low?
No. True range also considers gaps from the previous close. ATR averages true ranges over specified periods, which need not be daily. It uses price units and does not predict direction.
Does a larger market cap mean lower trading risk?
Not necessarily. Market cap does not establish liquidity, volatility, custody quality or the loss exposure of a leveraged position. Review the asset, venue and position separately.
Can a stop order or regular buying prevent losses?
Neither guarantees that outcome. A stop can execute away from its trigger, and a stop-limit can remain unfilled. Regular buying changes purchase timing but cannot guarantee profit or avoid a sustained decline.
