One row per year, 52 week slots straight across, grouped under the month they belong to. Cells are whole percent — hover one for the exact figure.
This page lays Bitcoin's entire history out one row per year, 52 week slots straight across, grouped under the month they belong to. It is the weekly grain of the Coinfuty returns grid — the same daily closes behind the monthly, quarterly and yearly views, re-cut to show how each year unfolded week by week.
A week's return is its last daily close against the last close of the previous week, in USD on UTC boundaries. The slots are fixed chunks of calendar days — each month splits into four or five equal pieces — not ISO weeks, so every year lines up column for column and the Median strip at the bottom can summarize all years per slot.
Weekly cells are rounded to whole percent to keep the strip readable; hover any cell for the exact figure. As with every grain here, the grid is a map of past behavior, not a forecast.
Bitcoin is down 0.2% so far in week 41 (October) of 2026, from the last daily close of the previous week slot to the close of 11 October 2026 (UTC). Coinfuty's weekly grid uses 52 fixed slots per year (5, 4 and 4 per quarter month), so this cell keeps moving until the slot ends.
Bitcoin returned −0.4% in week 40 (October) of 2026, its most recent completed week slot. The median return for that week slot on record is −0.3%.
Of the 40 completed week slots of 2026, Bitcoin's strongest was week 34 (August) at +25.6% and its weakest week 23 (June) at −14.4%. 15 of 40 closed positive. The current slot is excluded until it ends.
Across 16 prior years on record, the median return for week 41 (October) is +1.9% for Bitcoin. The best was 2010 at +59.6% and the worst 2011 at −6.6%; 10 of 16 closed positive.
Across 845 completed week slots on record, Bitcoin's best week was week 23 (June) 2011 at +189.0% and its worst week 42 (October) 2011 at −41.0%. 452 of 845 weeks (53%) closed positive.
The last daily close of the week slot divided by the last close of the previous slot, minus one, in USD on UTC boundaries. Slots are equal chunks of calendar days within each month, not ISO weeks, so columns align across years.
ISO weeks drift across month and year boundaries, which breaks column alignment in a year-by-year grid. Fixed slots — five in 31-day-heavy months, four elsewhere — keep every year comparable and let the Median strip aggregate the same slot across all years.
The Median strip under the grid answers this live: it is the all-years median for each of the 52 slots, and the strongest slot is its highest cell. The ranking moves as each new year lands, so read it from the live grid rather than any fixed answer.
