Market Cap
Share post
In Brief
Market cap (market capitalization) is the total value of a cryptocurrency, calculated by multiplying its current price by its circulating supply — used to gauge a coin's relative size and rank.
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.
Market Cap and Trust Wallet
Trust Wallet lets you track real-time prices and explore the market across 10,000+ cryptocurrencies on 100+ blockchains. Understanding market cap helps you weigh the size and risk of assets before you buy, store, or swap them — all from a non-custodial wallet where you keep full control of your private keys.
