Bitcoin Dominance
Bitcoin dominance is Bitcoin's share of the total market capitalization of all cryptocurrencies, expressed as a percentage. It shows how much of the crypto market's value sits in Bitcoin compared with everything else.
How it is calculated
The formula divides Bitcoin's market cap by the total market cap of all tracked crypto assets. Say Bitcoin is worth 1 trillion dollars and the whole market 2 trillion dollars. Bitcoin dominance is then 50%.
The result depends on what the data provider counts. Some include thousands of small tokens, others filter them out, so the same moment can show different dominance figures on different sites.
What moves it
Dominance rises when Bitcoin gains more, or loses less, than other crypto assets, and falls when altcoins outperform. In many past cycles, dominance rose during downturns, as investors moved towards the largest and most established asset, and fell during speculative phases, when money rushed into smaller tokens.
That pattern is why dominance is often linked to risk appetite and to the idea of altseason. It is a tendency observed in some cycles, not a rule. Developments such as spot Bitcoin ETFs, which only buy Bitcoin, can push dominance up for reasons unrelated to fear.
The stablecoin effect
Stablecoins are included in total crypto market cap. When investors sell volatile coins for stablecoins, the total market falls while stablecoins hold their value, which changes dominance even though no money moved into or out of Bitcoin. Some analysts therefore look at dominance excluding stablecoins, or at Bitcoin's performance against a specific altcoin such as ETH.
Reading it with care
Dominance is a ratio, so it says nothing about whether the market is rising or falling overall. Dominance can climb while Bitcoin itself drops, as long as altcoins drop more. Use it to understand relative performance and market structure, not as a signal to switch between assets.

Frequently asked questions
Does rising Bitcoin dominance mean the market is going down?
Not necessarily. It only means Bitcoin is doing better than the rest of the market. That can happen in rising markets, falling markets or sideways ones.
Why do different websites show different Bitcoin dominance?
Each provider tracks a different set of assets and calculates supply differently, which changes the total market cap used in the formula.
What is the link between Bitcoin dominance and altseason?
A sustained fall in dominance means altcoins are outperforming Bitcoin, which is how altseason is usually described. A falling ratio alone does not confirm or predict one.
