What is Market Cap?

Market capitalization (market cap) represents the total dollar value of a cryptocurrency. It’s calculated as:

Market Cap = Current Price × Circulating Supply

Market Cap Example

Bitcoin:

  • Price: $70,000
  • Circulating Supply: 19.5 million BTC
  • Market Cap: $70,000 × 19,500,000 = $1.365 trillion

Types of Market Cap

Circulating Market Cap

  • Uses coins currently in circulation
  • Most commonly quoted figure
  • Excludes locked/vesting tokens

Fully Diluted Valuation (FDV)

  • Uses total/maximum supply
  • Shows potential future market cap
  • Important for new tokens with low circulation

Market Cap Categories

Large Cap ($10B+)

  • Bitcoin, Ethereum
  • Most established
  • Lower volatility
  • Examples: BTC, ETH, BNB, SOL

Mid Cap ($1B-$10B)

  • Growing projects
  • Higher risk/reward
  • Examples: LINK, UNI, AAVE

Small Cap ($100M-$1B)

  • Higher volatility
  • Potential for large gains or losses
  • Less liquid

Micro Cap (Under $100M)

  • Very high risk
  • Often new projects
  • Low liquidity
  • Potential for manipulation

Why Market Cap Matters

1. Size Comparison

Compare cryptocurrencies regardless of price:

  • Coin A: $100 price, 1 million supply = $100M cap
  • Coin B: $1 price, 200 million supply = $200M cap
  • Coin B is “larger” despite lower price

2. Investment Decisions

  • Large caps: More stable, institutional-friendly
  • Small caps: Higher risk, higher potential return

3. Price Potential

Math example:

  • Coin at $1M market cap reaching $1B = 1,000x
  • Coin at $100B reaching $1T = 10x
  • Smaller caps have more room to grow

Market Cap Limitations

Doesn’t Show Liquidity

  • High cap doesn’t mean easy to sell
  • Actual trading volume matters

Can Be Manipulated

  • Low-supply tokens can have inflated caps
  • Wash trading increases apparent cap

Ignores Token Economics

  • Inflation rates
  • Unlocking schedules
  • Burn mechanisms

Circulating Supply Issues

  • Not always accurately reported
  • Lost/burned coins still counted
  • Locked tokens may unlock

Using Market Cap Wisely

Compare Within Categories

  • Compare ETH to SOL, not ETH to micro caps
  • Similar market caps = similar maturity

Watch Cap Changes

  • Rising cap without price increase = inflation
  • Falling cap with stable price = deflation

Consider FDV

  • If FDV >> Market Cap, future dilution coming
  • Important for new token investments
