Bitcoin Monthly Returns Calendar Since 2010

How the Bitcoin Monthly Returns Calendar Since 2010 works

A heatmap of Bitcoin’s monthly and annual returns from September 2010 to today, for comparing the same month across years and following each year’s sequence. Every cell discloses its data source and whether the current month is still provisional.

What you enter

• Range: Full history, Latest 10 years (the default on this page) or Current cycle (2024 onward)
• Show provisional current month (checkbox)
• Cell selection to inspect value, source and status
• Export: CSV or image

What it shows

• Month × year heatmap of returns (%) with the annual or YTD return
• Per-cell source note (rounded consensus, public cross-check, Binance archive, Binance daily) and provisional status
• Summary cards: positive month rate, best and worst observed month, strongest and weakest average month, latest completed month

How to use it

1. Choose Full history, Latest 10 years or Current cycle.
2. Read a row for one year’s monthly sequence and its total.
3. Read a column to compare the same month across years.
4. Click a cell to see its exact value, source and whether it is provisional.
5. Toggle the provisional month and export CSV or an image if needed.

Formula

Monthly return = UTC month-end close ÷ prior UTC month-end close − 1. Annual return = product of (1 + monthly return) − 1; the current year is labeled YTD.

Worked example

If December closes at $40,000 and January at $42,000: 42,000 ÷ 40,000 − 1 = +5%. Two months of +10% and −5% compound to 1.10 × 0.95 − 1 = +4.5%, not +5%.

How to read the result

• Compare a month’s average with how many years it was positive; a few extreme years can dominate averages.
• Annual figures compound monthly returns, so order matters.
• Provisional current-month values change with every daily close.

Limits and cautions

• Each calendar month has only one observation per year since 2010, so seasonality is not a reliable trading signal.
• Early-year values are rounded multi-market consensus references and may differ from other sources.
• Months without data stay empty instead of being filled with 0%.

Common questions

What has historically been Bitcoin’s best month?

The summary cards rank calendar months by average return across completed months. Check them directly, because the averages shift as new months complete.

Where does the monthly return data come from?

A rounded multi-market consensus reference for early history; recent months are recalculated from Binance BTCUSDT UTC daily closes and verified archives.

When is the previous month finalized?

At 02:17 UTC on the 2nd of each month, from the checksum-verified Binance daily archive, with a retry on the 3rd if needed.
