Bitcoin (BTC) largest recorded one-hour moves

Read window: 2016-10-25 06:00 UTC inclusive to 2026-10-25 06:00 UTC exclusive (candle start times). Only the last ten years and fully ended hours are read.

First stored candle start: 2019-01-01 00:00:00 UTC. Last stored candle start: 2026-10-25 05:00:00 UTC; it ends 2026-10-25 06:00:00 UTC.

68442 observed rows; 68442 valid hours; 0 invalid or off-hour observations skipped. 60 missing hourly timestamps between the first and last stored hours; time before the first or after the last observation is not counted as a gap.

10 zero-return hours excluded; 62722 additional same-date, same-side moves skipped; 5690 daily extremes outside the top ten omitted. Falls and rallies are deduplicated separately. Equal percentage moves select the earliest UTC hour, then the earliest date.

Valid candles have finite positive open, close, low and high prices, with both open and close inside the low–high range. Invalid quote volume is shown as unavailable without changing the price ranking. Missing observations may hide larger moves.

The 24-hour comparison is 100 × (close exactly 24 hours after the selected close / selected close − 1). All 24 subsequent hourly candles must be present at exact timestamps with valid prices. A gap, invalid prices or a follow-up that has not ended makes it unavailable; no nearby close is substituted.

The observed low and high do not reveal their intrahour order or a realized trade path. These spot candles describe neither execution opportunities nor liquidations, and do not establish lifetime or all-exchange records. Successful reads are cached for up to one hour.
