Bitcoin Dominance & Altcoin Season
Live reading
ContextDominance is 60.2%, above the 55% line: capital is concentrated in Bitcoin rather than spreading into altcoins. This is shown as context and does not vote.
What is Bitcoin dominance?
Bitcoin dominance is Bitcoinâs share of the total cryptocurrency market capitalization. At 60% dominance, six of every ten dollars in crypto sit in Bitcoin; the rest is spread across Ethereum and thousands of altcoins.
Dominance moves with relative performance. It rises when Bitcoin outperforms the rest of the market, which typically happens in downturns and early recoveries when capital hides in the most established asset. It falls when altcoins outperform, the pattern traders call altcoin season.
This page reads dominance from CoinGecko. Until September 2026 it was a counted signal, bullish when dominance sat below 55% in a market higher than 30 days earlier. The pairing mattered because dominance alone is ambiguous: it can fall while everything bleeds, if altcoins simply bleed slower.
Why it matters for the bull market
Mature bull markets have usually been broad. The classic cycle sequence is that Bitcoin leads and makes the first new highs, then confidence spreads and capital moves outward along the risk curve into large-cap and then small-cap altcoins, pushing dominance down while the whole market grows. Dominance under 55% inside a rising market was the signature of that phase in 2017 and 2021.
It stopped working as a vote. Bitcoin dominance has sat above 55% on every day since early 2025, so the vote could only say no, and it said no through most of the 2023 to 2025 bull market as well. This cycle concentrated capital in Bitcoin, helped by spot Bitcoin ETFs, which can only buy Bitcoin. A vote that can only give one answer carries no information, so dominance moved to context, where it still shows how broad a rally is without deciding whether there is one.
How it is used
Context indicator, not counted in the verdict. Dominance below 55% in a market that is higher than 30 days ago marked the broad, risk-on phases of past cycles.Frequently asked questions
What is Bitcoin dominance?
Bitcoinâs market capitalization as a percentage of the entire crypto market. It measures where capital sits within crypto, not whether the market is rising or falling.
What is altcoin season?
A stretch where most altcoins outperform Bitcoin, pushing dominance down while the total market grows. It has historically arrived in the later, broader phase of bull markets as risk appetite spreads outward.
Why 55%?
Historically, sustained readings below the mid-50s coincided with broad risk-on phases, while flights to safety pushed dominance well above it. It is a judgment call, and it is now a reference line on a context indicator rather than a vote.
Is rising dominance bearish?
Not by itself. Bitcoin-led recoveries raise dominance and are healthy, and the 2023 to 2025 bull market ran with dominance above 55% for most of its length. High dominance says a rally is narrow, not that it is over.
Why is dominance no longer counted in the verdict?
Because it has sat above 55% on every day since early 2025, so as a vote it could only say no. It moved to context in September 2026.
