Compounded price return for every calendar month on record. Read down a column for seasonality, across a row for the year's rhythm.
Ethereum's return calendar tells a different story from Bitcoin's, even though the two markets move together most of the time. ETH amplifies both directions: its strong months tend to stack during risk-on stretches when the ETH/BTC ratio is climbing, and its weak months cluster when capital rotates back into Bitcoin. Reading the monthly grid next to Bitcoin's makes those rotation phases easy to spot — the columns where ETH's cells run deeper in both directions.
The history here starts from Ethereum's first daily perpetual-futures candle in late 2019, which conveniently frames the modern era: DeFi summer 2020, the 2021 double-peak, the 2022 unwind and the ETF-era regime that followed. Use the Yearly tab to see how much of each year's result came from just one or two months — a recurring pattern in ETH's history.
The Median row under the monthly grid computes it live — the calendar month with the highest median ETH return across all recorded years is its highest cell. It shifts as new years land, so the live grid is the authoritative answer rather than any fixed month.
Each coin's history begins at its first daily perpetual-futures candle. Ethereum's USDT perpetual started trading on Binance in November 2019, a couple of months after Bitcoin's, so its grid has slightly fewer rows.
Loosely. The broad risk-on and risk-off months often match, but ETH regularly diverges when the ETH/BTC ratio trends — some of its best months arrived while Bitcoin was flat. The medians on each page are computed independently from each coin's own history.
