Bitcoin price history

Changed on

Daily BTC price time series, one point a day: the day's last price. Each point names the source its close came from (data[].source): Blockchain.com to 2025-08-31 and CoinGecko after it, except Kraken for 2026-08-28 and Coinbase for 2026-08-29 to 08-31 and 2026-09-14 to 09-29. Since 2026-10-01 each day's close is asked from CoinGecko; a day it does not answer is Coinbase's and says so, and the current day's point is the latest price so far, most often Coinbase's. sources lists each source served with its first and last date, and attribution carries "Powered by CoinGecko." whenever a CoinGecko close is served. Date ranges by tier:

  • Free: Rolling 30-day window
  • Basic: From January 1, 2025
  • Pro/Enterprise: All available data (from August 18, 2010)
