Bitcoin's 320-Day Cycle Points to a New Buy Window in 2027

By Juan Villaverde Reviewed by: Beth Canova

For over a month, I've remained consistent in my outlook for the rest of 2026 … 

• Prices would rally into an 80-day-cycle top in late September.
• Then cool off in an 80-day correction, bottoming between Oct. 23 – Nov. 12.
• Then, we’d see a rally to early December, likely bringing BTC to $90K.
• Finally, we’d end 2026 and move into 2027 in a steeper, 320-day correction. The bottom there is when I expect to find our next best buying opportunity. 

But this week, something shifted. 

I no longer think we’re just dealing with an 80-day-cycle correction. 

I now believe that Bitcoin’s (BTC, “B+”) Sept. 21, high — made near $87,000 — wasn’t just an 80-day top. I think it may have been a 320-day cycle top. 

And that changes how we should interpret the key dates my model has told us to watch.

This can get a bit technical, so let me explain.

My Forecasting Model is a forward-looking indicator that tells me when we should expect key trend reversals.

And my Crypto Timing Model follows the cycles of the crypto market, not the price action. 

Together with various macro indicators — namely liquidity and Treasurys — they help us target the moments when Bitcoin’s overall price direction changes.

What it doesn’t do is predict pricing. 

Because what I’ve found in my years studying crypto cycles is that timing matters far more than price when it comes to understanding markets.

So, I’ll start with what hasn't changed: the timing. 

I previously expected a low around now, and I still do. 

What has changed … is which cycle I’m tracking. By extension, that fundamentally changes how high I believe the rally that comes after will take us.

How could I get two cycles mixed? 

Because they tend to nest one inside the next. 

The 80-day cycle tracks Bitcoin’s medium-term movements. Four of those fit neatly into the 320-day cycle, which follows Bitcoin for about a year. 

Four of those, in turn, fit inside the longer four-year cycle. I called the bottom of that one in late June of this year. 

So, it is possible for a single high or low … to represent the top or bottom of both a shorter and a longer cycle.

That’s what I believe is happening here.

That part bears repeating: It’s the duration of this correction that has changed my outlook. 

Not how far Bitcoin has fallen. 

Indeed, despite the prolonged pullback, BTC has only dropped by about 20% from that Sept. 21 high as of this morning. 

That’s nothing to write home about in crypto. 

In fact, it wasn’t uncommon to see swings like that in an 80-day-cycle correction in the past. But with Wall Street’s entry into crypto in 2025, 80-day corrections have grown shallow in terms of price. 

Timewise, however, the cycles haven’t changed at all.

This correction has now lasted about 52 days. And it is still going. The average length of an 80-day cycle correction is about 30-45 days.

That this has gone longer — and is still in full swing — is a sign I can’t ignore.

Should this surprise anyone?

Not really. 

I've been saying since early October that this incoming rally — the one I expect will take us to the end of 2026 — isn't crypto’s next big buying opportunity. 

This simply confirms it. The big opportunity, in my view, will come in January.

Now, why am I so convinced a low is coming soon? 

Answer: Cross-asset correlations. 

The market weakness hasn’t just been limited to crypto. Stocks, gold, silver and — for the first time in a while — even oil all sold off together. 

That's a coordinated risk-off move. In typical fashion, crypto was among the first to turn down, back on Sept. 21.

Yet, my forecasting model now shows lows for all these assets in roughly the same window, during the first half of November.

• Bitcoin: Bitcoin has kept making new lows in recent days. But the exact day isn't the point. The window is what matters most. And we’re still in it.
• S&P 500 Stock Index: It saw a 20-week (roughly 160 days) cycle low signaled on Nov. 11.
• Nasdaq Semiconductor Index (SOX): The SOX is a proxy for the AI trade. My model had it topping between Sept. 21 and Nov. 1. The actual high came on Oct. 4. Now, it's calling a significant low.
• Silver: Silver's window for a 24-week cycle low centers around Nov. 4, however we don’t yet have confirmation.
• Gold: Gold’s forecast low was Oct. 26, within a window extending Oct. 6 through Nov. 15. Gold made a low on Oct. 30. But like silver's, it remains unconfirmed.

The dates differ slightly for different assets. Yet the margins of error run through mid-November, and the windows overlap. 

These forecasts don't have to be exact to be useful. They're timing windows. 

And landing within days of a forecast date, as gold just did, is already remarkable.

Why does this matter?

Because assets like these don't normally agree. That they do now is an anomaly worth watching. 

And that increases my conviction that we’re getting a risk-asset low about now.

I'm not saying these markets will trade together from here. But they sold off together, and my model has them turning together. 

Where they each go to next… depends on each individual asset. 

When it comes to crypto, my overall outlook still stands.

I expect one last tepid rally in 2026 before a deeper correction brings our next best buying opportunity, likely in late January 2027. 

The one caveat is I no longer believe BTC will hit $90,000 before we ring in the New Year. 

With this extra leg down, it’s more likely we’ll see Bitcoin climb back to the $85,000 level. Maybe we’ll retest the Sept. 21 high near $87,000. 

But I don’t expect we’ll go much higher.

That said, my Crypto Timing Model will still be monitoring the market in real time. 

And if any cryptos run early or if it sees a trading opportunity between now and then, I’ll send me a “buy” alert right away.
