What Is Bitcoin Dominance?
Bitcoin dominance measures Bitcoin's share of the total cryptocurrency market capitalization. For instance, if the total crypto market cap is $2 trillion and Bitcoin’s cap is $1 trillion, dominance stands at 50%. This metric is pivotal for predicting market cycles, especially the transition from Bitcoin-led rallies to altcoin booms.
Why Does Bitcoin Dominance Matter?
- Market Sentiment Indicator: High dominance (>65%) suggests risk-averse investors favor Bitcoin during uncertainty.
- Altcoin Season Precursor: Declining dominance (<50%) signals capital rotation into altcoins, often triggering bull runs.
- Profit-Taking Cycles: Investors frequently shift Bitcoin gains into high-potential altcoins as dominance drops.
Historical Bitcoin Dominance Patterns
2017 Bull Run
- Dominance plunged from 70% to 37%, fueling altcoins like Ethereum (ETH) and Ripple (XRP) to astronomical gains.
2021 Bull Run
- Dominance slid from 70% to 40%, with DeFi and NFT-linked altcoins outperforming Bitcoin (BTC).
Key Lesson: Altcoin rallies ignite when dominance breaks below 40%-45%.
