Market cap = Current Price × Circulating Supply. It sounds simple, but interpreting what this number means for investment decisions is where most investors go wrong. A $50B market cap says nothing about whether an asset is cheap or expensive without significant additional context.
Three Types of Crypto Market Cap
Three Types of Crypto Market Cap

Market Cap: Current Circulating Value
Market cap uses only the coins currently in circulation. For XRP: ~57 billion XRP in circulation × $0.80 price = ~$45.6B market cap. This is the number on CoinMarketCap and CoinGecko. It does not account for locked, vested, or unminted tokens.
Fully Diluted Valuation (FDV): Max Supply Value
FDV = Price × Maximum Total Supply. For XRP: all 100 billion XRP × $0.80 = $80B FDV. For tokens with high inflation or large unvested allocations, the FDV can be many multiples of market cap — indicating significant future selling pressure from unlocks.
Realized Cap: On-Chain Cost Basis
Realized cap values each UTXO at the price when it last moved on-chain — essentially the cost basis of all coins. When price > realized cap, the network is in profit on aggregate. The MVRV Ratio (market cap / realized cap) is a powerful cycle timing indicator.
Using Market Cap for Investment Decisions
Using Market Cap for Investment Decisions

- ✓Large cap (>$10B): Established, institutional grade, lower volatility
- ✓Mid cap ($1B–$10B): Growth stage, significant upside potential, moderate risk
- ✓Small cap (<$1B): Speculative, high potential, high loss risk
- ✓Never compare market caps across different asset types without context
- ✓Always check FDV / market cap ratio — ratios above 3:1 imply significant dilution risk
