Bitcoin monthly returns heatmap (2013–2026)

Method
Each cell is one calendar month’s return, measured from the previous month-end close to that month-end close (CoinGecko via cryptotools.tech/api (recent) + CryptoCompare histoday (history)). Green is up, red is down, and the deeper the colour the bigger the move. Bitcoin’s monthly swings are extreme by any traditional-asset standard. Figures exclude fees and taxes and are not investment advice; past performance doesn't predict future results.
