Response Data
data is an array; each element is one date's data, and timestamp is the millisecond timestamp of 00:00 (UTC) on that day. This endpoint has no request parameters and returns the full history at once: as of 2026-10-20, there are 1641 records in total, and the first is the earliest data point (2013-05-01). The data points are not daily; for example, the earliest few are 3 days apart. The example on the right keeps only the first 2.
bitcoin_dominanceIs Already a Percentage
94.3595means a Bitcoin dominance of 94.3595%; there is no need to multiply by 100 again.

Use Cases
| Scenario | Description |
|---|---|
| Observe Capital Rotation | A rising Bitcoin dominance means capital is more concentrated in Bitcoin; a falling dominance means altcoins are rising more, or capital is spreading to altcoins. |
| Combine with the Altcoin Season Index | Look at it together with the Altcoin Season Index to judge whether the current market is closer to a Bitcoin-led market or an altcoin-led market. |
| Estimate Total Market Cap | Use market_cap ÷ (bitcoin_dominance ÷ 100) to approximately estimate the total crypto market cap for the same period. |
| Long-Term Cycle Research | Use the historical data since 2013 to compare how Bitcoin dominance changed across past bull and bear cycles. |

FAQ
Is bitcoin_dominance 0.94 or 94%?
It is a percentage value: 94.3595 means 94.3595%; there is no need to multiply by 100 again.
Why is the data not one point per day?
There are 1641 records in total, starting from 2013-05-01, and the earliest few are 3 days apart, so the data points are not daily. When merging with other daily data, align by timestamp and do not assume the dates are consecutive.
Is market_cap Bitcoin's market cap or the market cap of the whole market?
It is Bitcoin's market cap (USD). If you need the total crypto market cap, you can approximately estimate it with market_cap ÷ (bitcoin_dominance ÷ 100).
Is the price field always present?
Not necessarily. 1 of the 1641 data points has no price, so check whether the field exists before reading it. This endpoint has no parameters and returns the full history each time (the response is about 190 KB).
Learn More: Bitcoin Dominance
What Is Bitcoin Dominance?
Bitcoin dominance is Bitcoin's market cap as a percentage of the total market cap of all cryptocurrencies, used to measure Bitcoin's share of the entire crypto market. The higher the dominance, the more market capital is concentrated in Bitcoin.
What Does a Rise or Fall in Bitcoin Dominance Indicate?
A rising dominance is common in phases when capital favors Bitcoin and altcoins perform weakly; a falling dominance is common in phases when altcoins rise more or many new coins are listed. When observing capital flows, it is best to also look at Stablecoin Market Cap History.
How Is Bitcoin Dominance Related to the Altcoin Season Index?
Both are used to observe the relative strength of Bitcoin and altcoins: Bitcoin dominance looks at market cap share, while the Altcoin Season Index looks at how altcoins as a whole perform relative to Bitcoin. The two usually move in opposite directions, and considering them together is more reliable.
