Bitcoin dominance (BTC.D) is Bitcoin's share of the total capitalization of all cryptocurrencies. It is one of the key market-structure indicators: it shows where capital is flowing. Rising dominance means Bitcoin is gaining faster than the market or falling slower — capital is hiding in the most liquid asset. Falling dominance means capital is spreading into altcoins, which has historically accompanied altseasons.
Dominance is read together with market direction. BTC price up with dominance up is a "Bitcoin rally" — alts lag behind. Price up with dominance down — money moves further out on the risk curve, into Ethereum and altcoins. Price down with dominance up — flight to quality within crypto. Price and dominance falling together is rarer and often means rotation into stablecoins.
The top-10 shares show how concentrated the market is: they are computed against the same total capitalization. A noticeable part of the "altcoin" share belongs to stablecoins — worth remembering when judging the real weight of speculative alts.
How to read it
Direction over level
The absolute level says little — the market has spent years at both 40% and 60%. The trend is what matters: a sustained dominance trend shows where capital has been going for weeks.
Cross-check with BTC price
The same dominance move means different things when Bitcoin rises versus falls. The four-quadrant matrix of price × dominance is the basic framework for reading market structure.
Mind the stablecoins
Stablecoins sit inside the "altcoin" part of market cap. Their growing share is a move into cash, not altcoin demand — even though BTC dominance formally falls.
Pair with the altseason index
Dominance shows capital flows from the top down; the altseason index counts how many coins actually beat Bitcoin. Together they give a more honest picture than either alone.
Frequently asked questions
- What is Bitcoin dominance?
- The ratio of Bitcoin's market capitalization to the total capitalization of all cryptocurrencies, in percent. Rising dominance means capital is concentrating in BTC; falling dominance means it is spreading across the rest of the market.
- Why is falling dominance linked to altseason?
- When altcoins grow faster than Bitcoin, their combined weight in total market cap increases and BTC's share mathematically shrinks. Sustained falling dominance in a rising market has historically accompanied periods of altcoin outperformance.
- How often does this page refresh?
- Dominance and market cap values update automatically several times per hour; the change is measured against the level 24 hours ago.
- Are stablecoins included in the calculation?
- Yes, total capitalization includes all cryptocurrencies, stablecoins among them. So part of the "altcoin" share is effectively cash parked in USDT, USDC and other stables.
