Bitcoin Dominance (BTC.D) is a key metric often cited in crypto news to assess market conditions. Historical trends show that when BTC.D reaches certain thresholds, it often signals the start of bull or bear cycles. This guide explores what BTC.D means, how to track it, and its historical correlation with market shifts.
What Is Bitcoin Dominance?
Bitcoin Dominance measures Bitcoin's market capitalization relative to other cryptocurrencies (altcoins). It reflects BTC's influence and importance in the crypto ecosystem.
Calculation: BTC.D = (Bitcoin Market Cap / Total Market Cap of Top 125 Cryptos) × 100
Example: If Bitcoin’s cap is $1T and the top 125 cryptos total $2.5T, BTC.D = 40%.

Why Bitcoin Dominance Matters
BTC.D reveals market sentiment:
- High BTC.D → Investors favor "safer" Bitcoin over volatile altcoins (bearish signal).
- Low BTC.D → Capital flows into altcoins, indicating speculative froth (potential bull peak).
Key Trends:
- BTC’s lower volatility vs. altcoins makes it a conservative hedge.
- Dominance spikes during downturns as investors exit altcoins.
Note: Pre-2017 data (90%+ dominance) is less relevant due to fewer altcoins.
