What is Bitcoin Dominance?

Last updated: 21 April 2026 · NavScope Intelligence

Bitcoin dominance (BTC.D) is Bitcoin's market capitalisation as a percentage of the total crypto market cap.

Formula: BTC Dominance = (Bitcoin Market Cap / Total Crypto Market Cap) × 100

Historical context: - 2013: ~90% (Bitcoin was almost the entire market) - 2018 ICO peak: ~33% (altcoin explosion) - 2021 bull run: ~40%–70% - 2025: ~55%–60%

How traders use BTC dominance: - Rising dominance: Bitcoin is outperforming altcoins — often signals "risk off" in crypto, or a BTC-specific bull run. Traders rotate from altcoins into BTC. - Falling dominance: Altcoins are outperforming Bitcoin — often called "altcoin season." Traders rotate from BTC into altcoins.

Frequently Asked Questions

What is a good Bitcoin dominance level?

There is no universal 'good' level — it depends on market cycle. Historically, BTC dominance above 60% suggests Bitcoin season; below 45% suggests altcoin season is active.

Does Bitcoin dominance affect altcoin prices?

Yes, strongly. When BTC dominance rises, capital often flows out of altcoins into Bitcoin. When it falls, altcoins typically outperform.
