Bitcoin Dominance Today: Live BTC Dominance Chart
What share of the crypto market Bitcoin holds today, versus Ethereum, stablecoins, and all other coins. Figures are read directly in your browser from public market cap data, with an hourly 7-day dominance history chart. Describes market composition, not financial advice.
The figures above are full dominance against the entire crypto market cap, sourced from CoinGecko /global, refreshed every 60 seconds in your browser.
BTC dominance history, 7 days, hourly (estimate)
Dominance against the top 50 coins, not the whole market. The “current” figure above is full dominance from CoinGecko, so its level differs from the line below. What's comparable is the direction.
Formula: Bitcoin market cap divided by the combined market cap of the top 50 coins in the same hour. Hourly market cap = hourly price (CoinGecko coins/markets 7-day sparkline) × current circulating supply. Cached in your browser for 1 hour.
What is Bitcoin dominance
Bitcoin dominance is Bitcoin's share of the crypto market cap. The calculation is simple: Bitcoin's market cap (price times circulating supply) divided by the market cap of all crypto assets, times one hundred. Being a ratio, it always sits between zero and one hundred percent, and moves whenever either side of that division changes.
That's where the most common mistake lies. Dominance isn't Bitcoin's price in another form. It's a relative number. Bitcoin can drop ten percent and its dominance still rise, as long as other coins drop fifteen percent over the same period. Conversely, Bitcoin can strengthen while its dominance erodes, if new money flows faster into assets other than Bitcoin.
One more thing affects the number regardless of market interest: how many assets are counted. Every newly listed token adds to the denominator, so Bitcoin's dominance shrinks bit by bit even if no Bitcoin holder sells. That's why comparing dominance across distant years needs care, the list of counted coins has changed.
How to read the dominance chart
The dominance line rises when Bitcoin's market cap grows faster, or shrinks more slowly, than other coins' market caps. It falls when the opposite happens. That's all the information it holds. The chart answers "whose share is growing", not "where is price going", and no position signal can be inferred directly from the shape of the line.
A few things dominance chart readers commonly watch: the slope direction over several weeks, which shows where market composition is shifting; the range of its moves, since dominance tends to swing within a fairly narrow band, so big jumps within days usually stem from specific events; and the comparison with the stablecoin share, since a growing stablecoin share means part of the market's value is sitting in dollar-denominated assets rather than rotating between coins.
Keep in mind that the history line on this page is calculated against the 50 largest coins, because dominance history against the whole market isn't available from free data sources. Its percentage level is therefore higher than the full dominance figure at the top of the page. The shape and direction of the two measures move together, but the numbers must not be swapped for one another.

FAQ
- What is Bitcoin dominance?
- Bitcoin dominance is Bitcoin's market cap as a share of the total crypto market cap, expressed as a percentage. If the whole crypto market is worth 4 trillion dollars and Bitcoin 2.2 trillion, dominance is 55%. It moves because of two things at once: Bitcoin's price and the price of every other coin. Dominance can rise even when Bitcoin falls, as long as other coins fall harder.
- Why is the history chart on this page called an estimate?
- Because its source differs from the number at the top. CoinGecko's free tier doesn't provide global dominance history, so the history line is built in-house: Bitcoin's market cap divided by the combined market cap of the 50 largest coins at the same hour (hourly price times current circulating supply). The denominator is 50 coins, not the whole market, so its percentage level is higher than full dominance. The "now" figure at the top of the page is full dominance from CoinGecko. What's comparable between the two is the direction and shape of the movement, not the absolute numbers.
- What does rising Bitcoin dominance mean?
- It means Bitcoin's market cap grew faster, or shrank more slowly, than other coins' market caps over the same period. It's a statement about share, not about price direction. Dominance can rise in a strengthening market or a weakening one. This page describes market composition and is not financial advice.
- Why are USDT and USDC grouped together?
- Both are stablecoins pegged to the dollar, so their share describes the same thing: how much of the market is sitting in dollar-denominated assets rather than in coins whose prices move. Each one's breakdown is still shown under the Stablecoin card. This share is read from CoinGecko market cap data, not from flows that can be traced wallet by wallet.
