Bitcoin’s outlook looks more optimistic after Binance founder CZ shared the charts today from October 2017. At the time, Bitcoin was trading at $4,319, but its daily volume was just over $1.1 billion. Over the next few weeks, prices jumped above $17,000. This was one of the hottest runs in Crypto history.
The post timing was in line at the end of September, with Bitcoin rising 4.57% to close at around $113,000. It may seem modest, but it broke the long trend. Historically, September has been one of Bitcoin’s weakest months, earning an average return of -4.9% over the past 14 years.
They don’t predict the future. And don’t get too excited.

Now we’re paying attention to October. The numbers tell the story that Bitcoin had a good run in 9 of the last 14 Octobers.
On average, there was a gain of 15.2%, with a median result of 13.1%. In a more memorable year, there will be +49% growth rate in 2017, +28.1% growth rate in 2020, +40% growth rate.
Even in slower years, this move has usually reached double digits.
Best scenario for Bitcoin in October 2025
Applying these numbers to current prices reveals that a typical October rally could raise Bitcoin to around $128,000-130,000. Repeating past cycles can lead to levels approaching $140,000.
Compared to 2017, the same results are not necessarily guaranteed, but the historical patterns are clear. September often sees weaknesses that turn into strength in October, and CZ reminders have brought that statistic back to the forefront, just as a new month begins.
