Bitcoin DominanceBTC.D
Bitcoin dominance is Bitcoin’s market capitalisation as a share of the whole crypto market. Stablecoin dominance is the same for stablecoins; a rising figure often means money is moving out of riskier coins.
Bitcoin dominance tells you how big Bitcoin is compared with the whole crypto market. Traders watch it to judge whether money is flowing into Bitcoin, into altcoins or into stablecoins.

Bitcoin dominance in plain words
Dominance is Bitcoin's market value divided by the value of the whole crypto market. At one point Bitcoin made up roughly 60% of that total.1
Chart sites compare that percentage with Ethereum, stablecoins and other coins.2
The total includes stablecoins, which the ECB put at roughly 8% of the market in one snapshot, so stablecoin swings move dominance too.3
How to read Bitcoin dominance
Get Bitcoin's market cap
Price times circulating supply; chart sites show it next to dominance.2
Get the total market cap
Check what the data source counts; some exclude wrapped, bridged and staked tokens to avoid double-counting.2
Divide and convert
BTC cap ÷ total cap × 100 gives dominance in percent.
Check stablecoins
Stablecoin share can fall simply because the rest of the market grows.4
Compare relative moves
If altcoins rise faster than Bitcoin, dominance falls even in a rally.4
Use it as context
Read it alongside price trend and volume, not as a buy or sell signal by itself.
Worked examples
Example 1 — Basic calculation
60% dominanceA hypothetical market: Bitcoin cap $1.2 trillion, total crypto cap $2.0 trillion.
| Dominance | $1.2T ÷ $2.0T = 0.60 |
| As a percent | 0.60 × 100 = 60% |
A reading near 60% matches the scale the IMF has described for Bitcoin's share.1
Example 2 — Altcoins outrun Bitcoin
−3.2 pointsHypothetically, Bitcoin's cap rises 40% from $1.2T to $1.68T while the other $0.8T rises 60% to $1.28T.
| New total | $1.68T + $1.28T = $2.96T |
| New dominance | $1.68T ÷ $2.96T = 56.8% |
| Change | 56.8% − 60% = −3.2 points |
Bitcoin gained but dominance fell, as when Ether and altcoins outgrew Bitcoin in one IMF quarter.4
Example 3 — Flight to stablecoins
Dominance unchanged at 60%Hypothetically total cap is $2.0T: Bitcoin $1.2T, stablecoins $0.2T, other coins $0.6T. Traders sell $0.1T of other coins into stablecoins.
| Bitcoin dominance | $1.2T ÷ $2.0T = 60% (unchanged) |
| Stablecoin share before | $0.2T ÷ $2.0T = 10% |
| Stablecoin share after | $0.3T ÷ $2.0T = 15% |
Dominance did not move, so check the stablecoin share separately; the IMF tracks it as its own percentage.4

Share of the pie
Beginner
Dominance is a share: Bitcoin's slice of total crypto market value, about 60 percent in the IMF's 2025 reading.1
What is in the denominator
Intermediate
Data sources may exclude wrapped, bridged and staked tokens to avoid double counting, so compare dominance only within one source.2
Stablecoins as a hidden variable
Advanced
When the wider market expands, the stablecoin share shrinks mechanically, which lifts the non-stablecoin shares, including Bitcoin's.4
Common mistakes
Treating it as price
Dominance can fall while Bitcoin rises.
Mixing data sources
Comparing a percentage from one site with another site's history.
Ignoring stablecoins
Missing that cash-like coins are inside the total.
Trading it alone
Using dominance as a standalone entry signal.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
