What is Market Cap?

tradernewbie · Editorial Team · Jul 29, 2026 · ~4 min read

Market Capitalization — The total market value of a cryptocurrency, computed as current price multiplied by circulating supply, used as a size and ranking metric.

How It Works

01 Formula: Market Cap = Current Price × Circulating Supply.

02 Circulating supply counts only coins publicly available and tradable, excluding locked or reserved coins.

03 Exchanges and data providers (CoinMarketCap, CoinGecko) aggregate prices across exchanges to compute a weighted average.

04 Market cap rankings help investors compare relative size: large-cap (>$10B), mid-cap ($1B-$10B), small-cap (<$1B).

Why It Matters

▸ Market cap indicates the relative size and maturity of a cryptocurrency project.

▸ Large-cap coins (Bitcoin, Ethereum) tend to be less volatile and more liquid.

▸ Market cap helps investors assess risk: small-caps offer higher potential returns but greater risk.

▸ It is a standard metric used by trackers, funds, and indices for portfolio construction.

Common Questions

Is market cap the best metric for crypto?

Market cap is useful but imperfect. It does not account for locked tokens, low liquidity, or wash trading. Fully diluted valuation (FDV) provides additional context.

What is the difference between market cap and FDV?

Market cap uses circulating supply; FDV uses total supply (including unlocked tokens). FDV can be much higher when many tokens are still locked.

Why do some coins have high prices but low market caps?

Price alone is meaningless. A coin with 1 million supply at $100 ($100M cap) is smaller than a coin with 1 billion supply at $1 ($1B cap).

Can market cap be manipulated?

Yes. Low-liquidity coins can have inflated market caps through wash trading or thin order books. Always check volume and liquidity alongside market cap.
