- Bitcoin is on track to finish September with a rare positive gain of 4.5 percent.
- Historically, a green September has preceded an average rally of over 50 percent in the fourth quarter.
- If the pattern holds, Bitcoin could target the $170,000 area by year-end.
In a powerful and uncommon rebuttal to its own gloomy reputation, Bitcoin is poised to close September in the black.
This is significant. For years the month has been the harshest in 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 flipped the script, potentially lighting the fuse for an explosive rally in the final quarter of the year.
A prophecy written into the charts
History doesn’t repeat exactly, but it often rhymes. In Bitcoin’s world, the rhyme of a green September is a powerful and bullish omen.
According to historical data, in the rare instances when Bitcoin closed September in positive territory — in 2015, 2016, 2023 and 2024 — the fourth quarter delivered spectacular results, with average returns rising to more than 53 percent.
In those years, Q4 returns ranged from an impressive 45 percent to a staggering 66 percent.
If this historical pattern repeats itself this year, Bitcoin could set its sights on the $170,000 region before the calendar flips to 2026.
The data show October typically acts as the launchpad for these strong moves, with an average gain of 21.8 percent, while November often continues the upward trend.
This seasonal effect has proven particularly profitable in post-halving years, when a potent mix of capital inflows and bullish positioning has driven the asset into a new phase of price discovery.
On-chain view: a bullish tide turning
That bullish seasonal setup is not just a statistical quirk; it is being corroborated by deeper on-chain currents.
Key on-chain metrics are now flashing green, signaling a meaningful shift in market dynamics.
The Spot Taker Cumulative Volume Delta (CVD), an important indicator that measures the difference between market buy and sell volume, has turned positive on a 90-day basis for the first time since mid-July.
This is a clear, direct sign that a “taker buy dominant phase” is underway—an environment in which buying pressure decisively outweighs selling activity.
At the same time, the Coinbase Premium Index has highlighted consistent and aggressive accumulation by U.S. investors during the third quarter.
The strong combination of these two on-chain metrics reinforces the view that a renewed wave of buying momentum is not only coming, it is already here.
The stage is set and the signals are favorable; the final quarter of the year could once again prove decisive and eventful for the world’s leading digital asset.
