What Is Bitcoin Dominance and Why It Matters for Crypto Markets
What Is Bitcoin Dominance?
Bitcoin dominance is a metric that reflects the percentage of the total cryptocurrency market capitalization that is accounted for by Bitcoin. In simple terms, it tells us how much of the total crypto market value is held in Bitcoin compared to altcoins (alternative cryptocurrencies).
Formula: Bitcoin Dominance = (Total Crypto Market Cap/Bitcoin Market Cap) × 100
This indicator is widely tracked by investors and analysts to gauge market trends, sentiment, and capital flows within the crypto space.
Why Does Bitcoin Dominance Matter?
- Market Sentiment Indicator
A rising Bitcoin dominance often signals risk aversion in the market. Investors tend to move capital into Bitcoin during uncertain times because it’s seen as the most stable and established cryptocurrency. - Altcoin Season Predictor
A declining Bitcoin dominance could suggest the onset of an “altcoin season”—a period when altcoins outperform Bitcoin in terms of price gains. This often happens when investors feel more confident and are willing to take on more risk. - Capital Flow Insights
Monitoring Bitcoin dominance helps traders understand where the money is flowing. Is it moving into safer assets like BTC, or into smaller, more speculative altcoins?
Historical Trends in Bitcoin Dominance
- 2017 Altcoin Boom: Bitcoin dominance dropped below 40% as Ethereum, Ripple, and other altcoins gained traction.
- 2020-2021 Bull Market: Bitcoin’s dominance surged past 70% before declining again as DeFi and NFTs drove altcoin interest.

How Traders Use Bitcoin Dominance
Traders use Bitcoin dominance in conjunction with price charts to make informed decisions:

- Low Dominance + Rising Altcoin Prices: Altcoin season likely.
- Falling Dominance + Falling BTC Price: Market-wide risk-off environment.
Final Thoughts
Bitcoin dominance isn’t a crystal ball, but it’s a powerful tool in any crypto investor’s toolkit. By understanding how it reflects investor sentiment and market trends, you can make more informed decisions—whether you’re trading altcoins, holding Bitcoin, or just starting your crypto journey.
