What Is Market Cap?
Market cap, short for market capitalization, is the total market value of a cryptocurrency. It's calculated by multiplying the current price of a single coin by the number of coins in circulation. Market cap is one of the most important metrics for understanding a crypto asset's size and ranking it against others.
A higher market cap generally indicates a larger, more established asset, while a lower market cap often signals a smaller, potentially more volatile project.
How Is Market Cap Calculated?
The formula is simple:
Market Cap = Current Price × Circulating Supply
For example, if a coin trades at $2 and has 50 million coins in circulation, its market cap is $100 million. Price alone doesn't tell you a project's size — a coin priced at $0.01 can have a far larger market cap than one priced at $1,000, depending on supply.
Market Cap Tiers
| Tier | Approximate Range | Characteristics |
|---|---|---|
| Large-cap | $10B+ | Established, lower volatility (e.g. BTC, ETH) |
| Mid-cap | $1B–$10B | Growing, moderate risk and volatility |
| Small-cap | Under $1B | Higher risk, higher potential volatility |
Why Does Market Cap Matter?
Comparing projects — ranks coins by total value, not just price per coin.
Gauging risk — larger caps tend to be more stable; smaller caps more volatile.
Portfolio decisions — helps balance exposure across asset sizes.
Spotting hype — a tiny project with a huge market cap may be overvalued.
Market Cap vs Fully Diluted Valuation
Market cap uses the circulating supply (coins available now).
Fully diluted valuation (FDV) uses the maximum supply (all coins that will ever exist).
A large gap between the two can signal significant future supply that may dilute the price as new coins enter circulation.
