BTC Dominance Calculator
See live Bitcoin dominance, compare BTC.D across different market universes, and calculate how Bitcoin and altcoin market-cap moves change the ratio.
Bitcoin dominance now
BTC.D is Bitcoin's share of total crypto market cap. The snapshot pairs the headline ratio with Bitcoin, non-Bitcoin, Ethereum, and stablecoin market cap context.
BTC dominance changes when the denominator changes
BTC.D depends on which assets count toward total crypto market cap. Compare the broad CoinLore reading with narrower top-50, top-100, and exclusion views.
Model BTC dominance from market moves
Separate Bitcoin from the rest of crypto and see how relative market-cap growth changes BTC.D.
Dominance scenario surface
Compare BTC and non-BTC market moves side by side. The 0% / 0% cell marks today's calculated BTC.D.
Stablecoin dilution calculator
Estimate how additional stablecoin market cap changes BTC.D if Bitcoin and the rest of the market do not move.
BTC dominance depends on what counts as crypto market cap
Different denominators produce different BTC.D readings
A broad-market BTC.D reading and a top-100 ex-stablecoins reading can differ at the same moment because each ratio uses a different denominator. The comparison above shows how large that difference is today.
That distinction matters during broad crypto rallies. Bitcoin can gain strongly in USD while BTC.D falls because other assets gained even faster.
What BTC dominance cannot show
BTC.D does not identify which altcoins are leading, whether market liquidity is improving, or whether a dominance move will continue. It is a market-share measure, not a directional price forecast.
For current market leadership, compare crypto performance versus Bitcoin.
Data and methodology
Live global market-cap and top-asset data come from CoinLore. Top-50 and top-100 variants use the current ranking snapshot. Stablecoin and wrapped / derivative-token exclusions rely on maintained symbol lists; they are not canonical market definitions.
What is BTC dominance?
BTC dominance is Bitcoin market capitalization divided by the market capitalization of the crypto universe used as the denominator. Different data providers can report slightly different values because their eligible asset universe differs.
Why does excluding stablecoins change BTC dominance?
Stablecoins add market capitalization to the denominator without adding to Bitcoin market capitalization. Removing them answers a different question: Bitcoin's share of non-stable crypto assets.
Can BTC dominance fall while Bitcoin rises?
Yes. If the rest of the crypto market grows faster than Bitcoin, Bitcoin can rise in USD while its share of total crypto market capitalization falls.
Is BTC dominance a trading signal?
No. BTC dominance is a market-share ratio. By itself, it does not tell you entry timing, price direction, or whether a move will continue.
