What Is Market Cap in Crypto?
Market capitalization (market cap) measures the total value of a cryptocurrency by multiplying its circulating supply by the current token price. It’s a key metric for ranking cryptocurrencies—Bitcoin (BTC), with the largest market cap, holds the top position.
Key distinctions:
- Market Cap: Reflects real-time value based on circulating supply.
- Fully Diluted Valuation (FDV): Estimates future value assuming maximum token supply is released.

Calculating Market Cap and FDV
Market Cap Formula
Market Cap = Current Price × Circulating SupplyExample: If BTC trades at $105,103 with 19.87 million coins circulating, its market cap is ~$2.09 billion.
FDV Formula
FDV = Current Price × Max SupplyExample: BTC’s FDV at 21 million max supply would be ~$2.21 billion.
Pro Tip: Platforms like CoinMarketCap and CoinGecko automate these calculations.
Crypto Market Cap Categories
| Category | Market Cap Range | Characteristics | Examples (2025) |
|---|---|---|---|
| Large Cap | >$10 billion | Lower risk, high liquidity | BTC, ETH, USDT, XRP, BNB |
| Mid Cap | $1–$10 billion | Growth potential, moderate volatility | Emerging DeFi tokens |
| Low Cap | <$1 billion | High risk/reward, volatile | New blockchain projects |

Why Market Cap Matters
Risk-Reward Assessment:
- Large Cap: Stable but limited upside.
- Mid/Low Cap: Higher growth potential with increased volatility.
Investor Strategies:
- Conservative: Focus on large-cap cryptos.
- Aggressive: Allocate a portion to mid/low caps for diversification.
Remember: Market cap alone isn’t enough—evaluate project fundamentals, team credibility, and market trends.
FAQs
Q: Can a cryptocurrency’s market cap change?
A: Yes! Market caps fluctuate with price and circulating supply adjustments (e.g., token burns).
Q: Is FDV always higher than market cap?
A: Typically yes, since FDV accounts for future token releases. Exceptions include fixed-supply coins like BTC.
Q: Are low-cap cryptos worth the risk?
A: They offer high growth potential but require thorough research—many fail to gain traction.
Q: How often should I check market caps?
A: Monitor weekly for portfolio rebalancing, especially during volatile market phases.
Final Thoughts
Market cap is a foundational metric for crypto valuation, but combine it with technical analysis and project research for informed decisions. Whether you’re a conservative investor or a risk-taker, understanding these categories helps tailor your strategy.
