What is Bitcoin dominance?
Bitcoin can fall 10% in a week and still end the week stronger.
Not stronger in price, but in share. If everything else fell further, Bitcoin now owns a bigger slice of crypto than it did. That share is Bitcoin dominance, and it moves for reasons that have nothing to do with Bitcoin's own chart.
A share, not a price
Dominance rises whenever Bitcoin does better than the rest, including when both fall.
When dominance rises, Bitcoin is outgrowing the rest of the market, often because investors are cautious and prefer the largest, oldest coin.
When dominance falls, other coins are growing faster. Long stretches of falling dominance are what people call altcoin season.
Dominance can move even when Bitcoin's price doesn't. If other coins fall, Bitcoin's share rises.
How dominance has moved
Bitcoin's share was above 90% until 2017. At the peak of the 2017–18 rally it fell to about a third as new coins boomed, and it dropped toward 40% again in 2021. In quieter periods money has tended to flow back toward Bitcoin, pushing dominance up.
Those swings are why traders watch it as a rough gauge of appetite for risk.
Why sites disagree
Each site divides by its own total, and totals differ depending on how many coins are tracked and how stablecoins are counted. A site tracking thousands of tiny coins will show a slightly lower dominance.
Compare dominance on the same site over time rather than between sites.
How stablecoins pull dominance down
Same Bitcoin, three readings. It's 60.0% with stablecoins in, 66.7% with them out, and 58.1% after $100 billion of new stablecoins, without anyone selling a single bitcoin.
Dominance is Bitcoin's market cap divided by the whole crypto market, and stablecoins are part of that whole. In an example market worth $3.0 trillion, Bitcoin is $1.8 trillion, other coins $0.9 trillion and stablecoins $0.3 trillion. Dominance is 1.8 divided by 3.0, or 60.0%.
Now suppose stablecoin issuers mint another $100 billion as people move cash into crypto. Nothing else changes. The total is $3.1 trillion and dominance falls to 58.1%, even though nobody sold a single bitcoin. Stablecoin supply has grown a great deal over the years, so part of any long-term fall in dominance can be this effect alone rather than money rotating into altcoins.
Some traders calculate dominance with stablecoins left out to remove that noise. In the same example, Bitcoin's share of the non-stablecoin market is 1.8 divided by 2.7, or 66.7%. You can do this yourself. Take Bitcoin's market cap, subtract the stablecoin total from the overall market cap, and divide. KryptoKap's market share tool shows stablecoins as their own slice, so the numbers are easy to pull out.
Same start, three different weeks
From 60%, dominance rose when everything fell, fell when everything rose, and jumped most when Bitcoin did nothing at all. It tracks the gap between the two, not Bitcoin's direction.
Start with Bitcoin at $1.80 trillion and everything else at $1.20 trillion, which is 60.0% dominance. In one week, Bitcoin falls 10% and the rest fall 20%. Bitcoin is now $1.62 trillion, the rest $0.96 trillion, and dominance rises to 62.8%. Both sides lost money, yet the reading went up.
In another week Bitcoin rises 20% and the rest rise 50%. Bitcoin reaches $2.16 trillion, the rest $1.80 trillion, and dominance drops to 54.5% during a strong rally for everyone. In a third, Bitcoin goes nowhere while the rest fall 30%, and dominance jumps to 68.2%, the biggest move of the three, with Bitcoin's price unchanged.
Real history has followed both patterns. Dominance fell to around a third in early 2018 when many newer coins were at their peak, then recovered as those coins fell much further than Bitcoin through that year. It climbed back above 60% during 2024 and 2025. Reading dominance properly means asking which side moved more, which is why it works best next to Bitcoin's own price chart and the total market cap.
Key terms
Dominance
Bitcoin's market cap divided by the total crypto market cap.
Altcoin
Any cryptocurrency other than Bitcoin.
Risk-on / risk-off
Money moving toward riskier assets, or away from them.
Stablecoin share
Part of the total that's in stablecoins, which affects dominance.
Where the number falls short
Whether Bitcoin is rising. Dominance can climb while Bitcoin's price falls, as long as everything else falls more.
Where the money came from. A rising share could mean buying Bitcoin, selling altcoins, or both.
A precise, shared number. Every site divides by its own total, so dominance on two sites rarely matches exactly.
What people get wrong
Rising dominance doesn't mean Bitcoin's price is rising. It only means Bitcoin is doing better than the rest.
Stablecoins count in the total, so dominance shifts when stablecoin supply grows or shrinks.
Why it matters
It's a quick read on where money is flowing within crypto, whether toward safety or toward riskier coins.
Common questions
Why does KryptoKap's dominance differ from other sites?
Each site tracks a different set of coins, so the total market cap underneath is slightly different.
How high or low can Bitcoin dominance go?
It has ranged from under 40% to over 70% since 2017. The number matters most as a direction, showing whether money is moving toward Bitcoin or away from it.
Should stablecoins count in Bitcoin dominance?
It depends on the question. Including them shows Bitcoin's share of all money in crypto. Leaving them out shows its share among coins whose prices actually move, without stablecoin issuance shifting the number. Both are valid. Just compare like with like over time.
Does falling Bitcoin dominance mean altcoin season has started?
Not necessarily. Dominance can fall because a few large altcoins rallied, because stablecoin supply grew, or because Bitcoin dropped. Altcoin season on KryptoKap means at least 75 of the top 100 coins beat Bitcoin over 90 days. Check the season meter alongside dominance before drawing that conclusion.
How is Ethereum dominance different?
It's the same calculation with Ethereum's market cap on top instead of Bitcoin's. Some sites show both. Together they tell you how much of the market sits in the two largest coins and how much is spread across everything else, including stablecoins.
