- Bitcoin is on track to close September with a rare positive gain of 4.5 percent.
- Historically, a green September has preceded an average gain of more than 50 percent in the fourth quarter.
- If the pattern holds, Bitcoin could be eyeing the $170,000 region by year-end.
In a powerful and uncommon reversal of its gloomy history, Bitcoin is poised to finish September in positive territory.
This is a notable achievement. September long carried the reputation of being the harshest month on the crypto calendar—a near-constant sea of red that earned it the ominous nickname “Red September.”
But this year’s 4.5 percent rise flips that narrative and may have just pulled the pin on an explosive rally for the final quarter of the year.
Patterns Written in the Data
History doesn’t repeat exactly, but it often rhymes. In Bitcoin’s world, a green September has been a powerful, bullish rhyme.
According to historical data, in the rare years Bitcoin closed September positively—2015, 2016, 2023 and 2024—the fourth quarter delivered striking returns: the average gain exceeded 53 percent.
In those years, fourth-quarter returns ranged from a robust 45 percent to an astonishing 66 percent.
If that historical pattern reasserts itself this year, Bitcoin could be looking toward the $170,000 area before the calendar flips to 2026.
Data show October typically acts as a launchpad for these strong moves, with an average gain of 21.8 percent, while November tends to continue the ascent.
This seasonal effect has been particularly profitable in post-halving years, when a potent mix of fresh capital inflows and bullish market positioning combine to push the asset into a new phase of price discovery.
A Blockchain Perspective: Bullish Flows Take Hold
This bullish seasonal pattern is not mere statistical coincidence; it is corroborated by deep currents observed on the blockchain itself.
Key on-chain indicators are now flashing green, signaling a meaningful shift in market momentum.
The cumulative volume delta for spot takers (CVD), an important metric tracking the difference between market buy and sell volumes, turned positive on a 90-day basis for the first time since mid-July.
That is a clear, direct sign that a “taker-buying dominance” phase is underway—a period when buying pressure decisively outweighs selling activity.
At the same time, the Coinbase premium highlights steady and aggressive accumulation by U.S. investors throughout the third quarter.
The convergence of these two key on-chain metrics strengthens the view that a fresh wave of buying momentum is not just imminent—it’s already in motion.
The stage is set, signals are aligning, and the final quarter of the year could once again prove decisive and explosive for the world’s leading digital asset.
