Bitcoin reliably rallies in October.
In 9 years of Bitcoin data, October closed higher 7 times (78%), with a median of +11.0% against +0.2% for the other months. It ranks #2 of 12 by median. But a month that rises 51% of the time would rise at least 7 times in 9 years by luck alone 10% of the time, so 9 data points can't settle it.
| Year | October return |
|---|---|
| 2025 | -3.9% |
| 2024 | +11.0% |
| 2023 | +28.5% |
| 2022 | +5.5% |
| 2021 | +39.9% |
| 2020 | +28.0% |
| 2019 | +10.3% |
| 2018 | -3.8% |
| 2017 | +47.6% |
How this was checked. Bitcoin's month-end close against the previous month-end close (Binance BTC/USDT, from 2017). 'By luck alone' is the exact binomial chance of that many up years if the month were ordinary.
