- Bitcoin is poised to finish September with a rare positive gain of 4.5 percent.
- Historically, a green September has preceded an average Q4 rally of more than 50 percent.
- If the pattern holds, Bitcoin could target the $170,000 range before the year ends.
In a striking and uncommon reversal of its own gloomy reputation, Bitcoin is on the verge of closing out September in positive territory.
This is no small feat. September has long been the harshest month on the crypto calendar, a persistent sea of red that earned it the ominous nickname “Red September.”
But this year a 4.5 percent gain has rewritten the script, and in doing so it may have lit the fuse for an explosive rally into the final quarter of the year.
A forecast written in the charts
History doesn’t repeat exactly, but it often rhymes. In the Bitcoin world, a green September is a powerful, bullish rhyme.
According to historical data, in the rare instances Bitcoin has closed September in positive territory — 2015, 2016, 2023 and 2024 — the final quarter produced spectacular returns, with average gains rising to more than 53 percent.
In those years, Q4 returns ranged from a strong 45 percent to an impressive 66 percent.
If the historical pattern repeats this year, Bitcoin could eye the $170,000 area before the calendar flips to 2026.
The data shows October typically serves as the launchpad for these powerful moves, with an average gain of 21.8 percent, while November often continues the advance.
This seasonal effect has been especially lucrative in years following a Bitcoin halving, when a potent mixture of capital inflows and bullish market positioning combine to push the asset into a new phase of price discovery.
On-chain outlook: a bullish tide turns
This bullish seasonal setup is not merely a statistical anomaly; it’s being actively confirmed by the deeper currents of the blockchain itself.
Key on-chain metrics are now flashing green, signaling a meaningful shift in market momentum.
Spot Taker Cumulative Volume Delta (CVD), a key indicator tracking the difference between market buy and market sell volumes, has turned positive on a 90-day basis for the first time since mid-July.
That’s a clear and direct signal that a “Taker Buy Dominant Phase” is underway—a period where buying pressure decisively outpaces selling activity.
At the same time, the Coinbase premium index has highlighted consistent and aggressive accumulation by U.S. investors through the third quarter.
The strong alignment of these two important on-chain metrics reinforces the view that a new wave of buying momentum is not only coming—it is already here.
The stage is set, the signals are aligned, and the final quarter of the year could once again prove to be a decisive and explosive period for the world’s leading digital asset.
