Market Capitalization (Market Cap)

Market capitalization is calculated by multiplying a coin's current price by its circulating supply: the number of coins actually available and trading in the open market. The result is a single dollar figure that lets traders compare projects with very different unit prices on equal footing, since a coin trading at $0.01 can easily be worth more in aggregate than one trading at $100.

The metric is used both for individual assets and for the crypto market as a whole. Analysts commonly group coins into large-cap, mid-cap, and small-cap tiers, a classification that mirrors how public float is used to value companies on a stock exchange. Large-cap coins such as Bitcoin and Ethereum tend to be more liquid and less volatile than small-cap tokens, where even a modest buy or sell order can move the price sharply.

Market cap has real limitations. Because it only counts circulating coins, it can understate a project's true dilution risk when a large share of supply sits in vesting contracts scheduled to unlock later; that fuller picture is better captured by fully diluted valuation. The figure also assumes every circulating coin could be sold at the last traded price, which rarely holds for thinly traded assets, and it can be distorted by wash trading or by a token launched with a deliberately small initial float.

Despite these caveats, market cap remains the most widely referenced yardstick for ranking cryptocurrencies and gauging how the broader market is shifting between risk-on and risk-off phases.
