What Bitcoin dominance tells you

Dominance answers a different question from price. Price says what one Bitcoin is worth; dominance says how much of the money in crypto is sitting in Bitcoin rather than anywhere else. The two come apart regularly — a day when Bitcoin drops 3% and the average altcoin drops 6% is a day dominance goes up. Traders watch the direction for rotation: capital concentrating in Bitcoin when conviction is thin, and spreading out into smaller coins when it returns. Read it as a trend over weeks, because a single day mostly reflects which corner of the market moved hardest.

Frequently asked questions

What is Bitcoin dominance?

Bitcoin dominance is Bitcoin's market capitalisation expressed as a percentage of the market capitalisation of all cryptocurrencies. At 50% dominance, half of every dollar held in crypto is held in Bitcoin. It is a measure of where money sits, not of Bitcoin's price: dominance can rise on a day Bitcoin falls, if altcoins fall further.

What does rising Bitcoin dominance mean?

Rising dominance means capital is concentrating in Bitcoin relative to the rest of the market. That usually happens in two situations: a risk-off stretch where traders rotate out of smaller coins into the largest one, or a Bitcoin-led rally that altcoins do not keep up with. Falling dominance is the mirror image and is the condition traders usually mean by an altcoin season.

How is Bitcoin dominance calculated?

Divide Bitcoin's market capitalisation by the total market capitalisation of all tracked cryptocurrencies, then multiply by 100. Market capitalisation is circulating supply multiplied by price, so dominance shifts when prices move and when supply changes. Different sites publish slightly different figures because they track different numbers of assets and treat stablecoins and wrapped tokens differently.

What is a high or low Bitcoin dominance?

Bitcoin was effectively the entire market at close to 100% in 2013. Dominance fell under 40% at the height of the 2017 and 2021 altcoin runs, and has spent most of the period since between roughly 40% and 60%. There is no level that mechanically signals a top or a bottom, which is why dominance is read as a trend rather than as a threshold.

Methodology

The dominance, market cap and volume figures at the top of this page come from Coinlib's market feed, refreshed every five minutes, and cover the full set of tracked assets. The 30-day chart is computed separately from Coinlib's own daily snapshots and measures Bitcoin's share of the combined top-100 market cap, so it runs about a point below the headline figure and should be read for its direction rather than its level. Market capitalisation is circulating supply times price throughout. Published figures differ between sites because each tracks a different number of assets; this page states which basis each number uses rather than blending them.
