Why is Bitcoin Strong in October? Understanding the Market through Anomalies and Data
The most performant period for Bitcoin is nearly upon us. Historical market data shows that October typically sees significant price increases for Bitcoin and other cryptocurrencies, earning it the nickname 'Uptober' among investors and traders. Notably, October marked the beginning of a bullish phase leading up to the end of the year in both 2020 and 2021.
Several factors contribute to this trend, including the halving cycle, institutional investments, and anticipation of the year-end market. Currently, in the United States, overlapping factors such as cryptocurrency regulations, economic conditions, and interest rate policies continue to fuel optimism for a vibrant crypto market.
Will October 2025 also deliver a historic bull run as in previous years?
October Records an Average and Median Increase of 20%
October holds a special significance for Bitcoin and other cryptocurrencies. According to data from the market analysis platform CoinGlass, between 2013 and 2024, Bitcoin only recorded a negative monthly performance in October twice, in 2014 and 2018. While February also saw only two negative months during the same period, its average performance was 13.12%, and its median was 12.21%. However, October surpasses these figures with an average increase of 21.89% and a median of 21.20%, consistently delivering high positive returns. Even excluding the results for 2025, the figures for February would still only hover around 15%, not reaching October's levels.
