Dominance is calculated as Bitcoin's own market capitalisation divided by the combined market capitalisation of every cryptocurrency, expressed as a percentage. It's a ratio between two figures rather than a price or a standalone value indicator, so it moves whenever Bitcoin's market capitalisation changes relative to the rest of the market, not only when Bitcoin's own price moves.
Market participants often track dominance as a rough gauge of sentiment: a rising figure is commonly read as capital concentrating in Bitcoin relative to other coins, while a falling figure is often read as altcoins gaining ground relative to Bitcoin. It's worth treating this as context rather than a precise signal, for a few reasons. Dominance can shift because of new coins being added to the total market calculation, large stablecoin issuance changing the denominator, or a small number of large-cap coins moving sharply, none of which necessarily reflects a broad shift in sentiment. Because it's a relative ratio, it can also change even when Bitcoin's own price is flat, simply because other coins are moving faster in either direction. It's commonly used as a rough sentiment gauge, not a precise trading signal, so it should be read as general context rather than a trading signal or financial advice.
Key takeaways
- Bitcoin dominance is Bitcoin's market capitalisation as a percentage of the entire cryptocurrency market's combined market capitalisation.
- It's a relative ratio, so it can rise or fall even without Bitcoin's own price changing, if altcoin values move differently.
- It's commonly used as a rough sentiment gauge, not a precise trading signal, so it's best read as context rather than financial advice.
Bitcoin Dominance — frequently asked questions
What does rising Bitcoin dominance mean?
It means Bitcoin's share of the total crypto market capitalisation is increasing relative to other coins, which is often interpreted as capital favouring Bitcoin over altcoins, though the underlying reasons can vary.
Does high dominance mean Bitcoin's price is going up?
Not necessarily. Dominance is a ratio, so it can rise even if Bitcoin's price is flat or falling, as long as altcoin values are falling faster.
