Crypto market capitalization shows how big a cryptocurrency really is.

The formula is simple:

Market Cap = Token Price × Circulating Supply

If a coin is $10 and 10 million tokens exist, its market cap is $100M. Platforms like CoinMarketCap and CoinGecko rank coins using this number.

Why Market Cap Matters

Compare projects fast: A $5B coin is obviously more established than a $500M one.

Portfolio guidance: Large caps like BTC/ETH = stability. Small caps = high risk, high swings.

Industry benchmarks: Crypto indexes like CMC100 use market cap to track the biggest players.

Circulating Supply vs Total Supply

Circulating: Tokens currently in the market.

Total/Max supply: Includes locked, vested, or future tokens.

Market cap only uses circulating supply because that reflects real demand.

Market Cap vs FDV

FDV = Current Price × Max Supply

FDV shows what a project might be worth if all tokens were released.

A low market cap but huge FDV = future dilution risk.

Bottom Line

Market cap helps you see the size, strength, and position of a crypto project — but it’s not enough on its own. Use it with FDV, token unlock schedules, liquidity, and volume to judge real value.
