Bitcoin ended October 2026 down 7.32%, its weakest October since 2014 in CoinGlass’s monthly data. The decline ended a three-month run of gains that began in July.
Bitcoin ended October 2026 down 7.32%, its weakest October since 2014. CoinGlass’s monthly price table shows a fall from the September closing price of $83,553.85 to $77,434.75 at the end of October, a difference of $6,119.10 per bitcoin.
In the series KriptoMeta reviewed on November 2, Bitcoin last suffered a larger October decline in 2014, when it fell 12.57%. It also fell 3.95% in October last year. Bitcoin has now posted consecutive October losses for the first time since 2011 and 2012.
October ends a three-month run of gains
Bitcoin rose 7.27% in July, 25.05% in August and 6.37% in September before declining in October. Each monthly percentage uses the previous month’s closing price as its starting point, so adding the three percentages does not give the cumulative gain over those months.
Traders use the nickname “Uptober” to express expectations of an October rally. In CoinGlass’s series, 11 of the 17 Octobers from 2010 through 2026 ended higher and six ended lower.
How the monthly loss is calculated
CoinGlass compares each month’s final daily closing price with the previous month’s closing price. For October, divide $77,434.75 by $83,553.85, subtract one and multiply by 100. The result is approximately minus 7.32%, rather than the gap between the month’s highest and lowest prices.
CoinGlass says each daily period ends at 00:00 UTC, which is 03:00 in Türkiye. Its Bitcoin prices come from US-dollar spot markets on major crypto exchanges, using trading pairs with long histories. The provider does not disclose the weight assigned to each exchange.
An investor’s profit or loss depends on the purchase price, whether the bitcoin has been sold and the fees paid. A 7.32% monthly price decline does not mean every holder lost that percentage. Comparing prices on two dates also cannot establish how much cash entered or left the market.
Past Novembers include sharp gains and losses
KriptoMeta compared the 16 completed Novembers from 2010 through 2025 using CoinGlass’s downloaded monthly data. Bitcoin rose in 10 and fell in six. The arithmetic mean was 34.95% and the median was 10.26%. To find the median, sort the returns and take the average of the two middle values.
The 453.64% gain in November 2013 pulls the arithmetic mean higher. Removing only that year lowers the average for the remaining 15 Novembers to about 7.03%.
| Year | October | November |
|---|---|---|
| 2020 | +27.79% | +42.41% |
| 2021 | +40.03% | −7.03% |
| 2022 | +5.48% | −16.23% |
| 2023 | +28.55% | +8.78% |
| 2024 | +10.87% | +37.36% |
| 2025 | −3.95% | −17.49% |
October gains preceded November losses in 2021 and 2022, while both months finished higher in 2023 and 2024. Larger losses occurred further back: Bitcoin fell 36.41% in November 2018.
At 05:08 UTC on November 2, the CoinGlass page showed Bitcoin at $78,426, up about 1.28% since the start of November. CoinGlass updates the current month with the latest price. Because November is still under way, the 1.28% gain was excluded from the 16-year calculation above.
Bitcoin’s rise in 10 of the past 16 Novembers does not establish its chances of rising in November 2026. The monthly price table does not say why investors bought or sold, so it cannot by itself explain October’s loss.
