Bitcoin Dominance
Bitcoin's share of total cryptocurrency market capitalisation — a widely watched indicator of the crypto market cycle, with rising dominance typically signalling risk-off conditions and falling dominance signalling 'altseason'.
The macro regime is unambiguously STAGFLATION DEEPENING. The three-pillar structure remains intact and strengthening: (1) Energy-driven inflation shock — WTI at $104-111, +40% in 1M, flowing through PPI (+0.7% 3M, accelerating) into a CPI/PCE pipeline that has not yet absorbed the full pass-through,…
What Is Bitcoin Dominance?
Bitcoin dominance (BTC.D) is the ratio of Bitcoin's market capitalisation to the total cryptocurrency market capitalisation, expressed as a percentage. It is typically tracked in real time on platforms like CoinMarketCap and TradingView.
Example: If Bitcoin's market cap is $1.5 trillion and the total crypto market is $3 trillion, Bitcoin dominance is 50%.
Historical Context
- 2017: BTC dominance fell from ~87% to ~37% during the ICO bubble (altcoin mania)
- 2018–2019: Rose back to ~70% as altcoins collapsed and BTC held better
- 2020–2021: Fell to ~39% during the DeFi summer and NFT/altcoin bull run
- 2022–2023: Rose back above 50% as the bear market hit altcoins harder
Dominance as a Market Cycle Indicator
Rising BTC dominance typically signals:
- Bear market or risk-off environment within crypto
- Investors rotating from altcoins into Bitcoin as a relative safe haven
- Capital exiting crypto staying in BTC rather than leaving entirely
Falling BTC dominance (altseason) typically signals:
- Late-stage bull market where retail is speculating on smaller, higher-beta assets
- Specific sector rotations (DeFi, Layer 1s, NFTs, memecoins)
- Increased risk appetite within crypto
The ETH Comparison
The Ethereum/Bitcoin ratio (ETH/BTC) is also closely watched. When ETH gains on BTC, it often signals a broader altcoin bull market. When BTC outperforms ETH, more defensive positioning within crypto.
Limitations
Dominance is sensitive to stablecoin market cap fluctuations (large stablecoin issuance dilutes all non-stablecoin dominance). Some analysts strip out stablecoins for a cleaner measure.
What to Watch
- Is BTC.D above or below 50%? (50% is a historically meaningful level)
- Direction and rate of change
- BTC.D behaviour relative to the overall crypto market cap
