Bitcoin experienced a significant decline in October 2026, dropping 7.3% according to CoinTelegraph. This marks a consecutive yearly loss for the cryptocurrency during a month that has historically yielded strong returns.

Following a similar downturn in October 2025, Bitcoin's recent performance challenges its reputation for seasonal strength in the final quarter of the year. Market observers will be watching closely to see if this trend signals a shift in Bitcoin's typical price cycles.

For Japanese investors, who actively engage in both crypto and FX markets, such volatility underscores the importance of cautious portfolio management amid changing seasonal patterns.
