Market cap (short for market capitalization) is one of the most important metrics in crypto. It represents the total value of a cryptocurrency and is calculated with a simple formula:
Market Cap = Current Price x Circulating Supply
For example, if a coin trades at $50,000 and there are 19 million coins in circulation, its market cap is $950 billion. Market cap helps investors compare the relative size of different cryptocurrencies and assess their position in the broader market.
Cryptocurrencies are often grouped by market cap:
- Large cap (above $10 billion) – Established projects like Bitcoin and Ethereum. Generally considered less risky but with slower growth potential.
- Mid cap ($1–10 billion) – Well-known projects that still have significant room to grow but carry more risk.
- Small cap (below $1 billion) – Newer or niche projects. Higher potential returns but much more volatile and risky.
Important things to keep in mind about market cap:
- Price alone is misleading – A $1 token with 100 billion supply has a larger market cap than a $1,000 token with 1 million supply.
- Fully diluted valuation (FDV) – This metric uses the maximum supply instead of circulating supply, giving a picture of the project's value if all tokens were released.
- Market cap does not equal money invested – It reflects current price times supply, not the total amount of capital that flowed into the asset.
You can track market caps on aggregators like CoinGecko and CoinMarketCap, or on exchanges such as Coinbase and Binance.
