Bitcoin’s first three days of October have historically been its weakest three-day stretch of the month, averaging a 0.66% decline.

2026 has already held up better.

Bitcoin closed September at $83,574 and October 3 at $84,743, a gain of 1.40%. On a like-for-like basis, from the October 1 close to the October 3 close, BTC slipped just 0.14%, compared with the historical average decline of 0.66%.

As of October 4, Bitcoin is trading near $85,132, around 1.86% above its September close. Since the day is still underway, that number may change.

September was also stronger than usual, finishing up 6.39% versus a historical average decline of 4.02%. October has made a solid start too.
