Dominance history
Daily readings since 24 July 2026 · recorded automatically each morning.
How to read it
Rising dominance — money favouring Bitcoin over altcoins; typical of cautious or institutional-led markets. Falling dominance — capital rotating into altcoins; historically the marker of speculative phases. Pair it with the Fear & Greed Index for the market's mood alongside its composition.
Fifteen years of dominance in six eras
Our own daily series is young — but the metric's history is long and unusually tidy: every major market phase since 2017 has left a distinct dominance signature. Reading today's number is easier with the map behind it.
The only game in town
Crypto essentially was Bitcoin. Early alternatives existed, but dominance held near-total.
The ICO collapse of dominance
The token-issuance boom dropped Bitcoin below half the market for the first time — the original "altcoin season", and the origin of the metric’s popularity.
Recovery and consolidation
The ICO class of 2017 faded and capital consolidated back to Bitcoin through the bear market and the 2020 recovery.
DeFi and the second alt wave
Ethereum, DeFi and NFTs drove the second great rotation. Dominance halved inside a year — the modern reference point for what a full altcoin cycle looks like.
Flight to quality
Terra, Celsius and FTX collapsed altcoin confidence. Money that stayed in crypto moved up the quality curve, and dominance ground higher through the bear.
The institutional era
Spot Bitcoin ETFs opened a channel that pours new capital specifically into Bitcoin — a structural tailwind for dominance that previous cycles never had. Today’s reading is above.
How people actually use this number
🧭 A regime gauge
Trending-up dominance says the market is Bitcoin-led: cautious, institutional, consolidation-minded. Trending down says risk appetite is spreading outward. Neither predicts price — they describe which market you're standing in.
🔄 An alt-season early warning
Sustained falls — weeks, not days — have historically marked altcoin rotations, and sharp reversals their endings. Altcoin holders watch dominance the way sailors watch barometers: not for certainty, for pressure.
⚠️ With its caveats on
Stablecoins sit in the denominator, so their growth drags dominance down without a single trade. ETFs pour new money specifically into Bitcoin. Comparing today's level to 2017's without those shifts in mind overreads the chart.
FAQ
What is Bitcoin dominance?
Bitcoin’s market capitalisation as a percentage of the entire crypto market. At 60% dominance, six of every ten dollars in crypto sit in Bitcoin. It is a composition measure, not a price — Bitcoin can fall while its dominance rises, if everything else falls harder.
Why do people watch it?
It shows where money is flowing. Rising dominance usually means capital is favouring Bitcoin (often in cautious markets); falling dominance means money is rotating into altcoins — historically a feature of speculative phases, sometimes called “altcoin season”.
What moves it?
Relative performance. New capital entering via Bitcoin ETFs lifts it; altcoin rallies lower it; stablecoin growth nudges it down without any trading at all. Long-term, dominance has ranged from above 90% (pre-2017) to below 40% (2018 and 2021 altcoin peaks).
What is "altcoin season"?
A stretch where most large altcoins outperform Bitcoin — visible here as dominance falling steadily. The classic examples (early 2018, mid 2021) both followed big Bitcoin rallies, as profits rotated down the risk curve. They also both ended with altcoins falling much harder than Bitcoin on the way back.
Does high dominance mean Bitcoin is doing well?
Not necessarily — it means Bitcoin is doing well relative to altcoins. In hard sell-offs, dominance often rises while Bitcoin itself is falling, because money that stays in crypto retreats to its largest asset.
The other half of the rotation picture: the altcoin season index measures how many altcoins are actually beating Bitcoin right now.
