Bitcoin Dominance

Bitcoin dominance is Bitcoin’s share of the entire crypto market’s value — its market capitalization divided by the market cap of all cryptocurrencies combined, shown as a percentage.

How it works

If Bitcoin’s market cap rises faster than the rest of the market, its dominance climbs; if altcoins rise faster, dominance falls. The figure therefore reflects not Bitcoin’s price alone but how it is performing relative to everything else, which is why it can drop even while Bitcoin’s price rises. Because stablecoins are counted in the total market cap, large flows in and out of them can nudge the ratio too.

Why it matters

Traders watch dominance as a gauge of market mood. Rising dominance often signals caution, with capital concentrating in Bitcoin; falling dominance can indicate appetite for riskier altcoins, a pattern sometimes called “alt season.” It is a sentiment indicator, not a precise predictor.

Example

If Bitcoin makes up half of all crypto value, its dominance is 50%.
