How Long Bitcoin Bear Markets Last — And What the Data Says About the Bottom
Bitcoin's four-year cycle isn't a physical law. It's a pattern drawn from three completed cycles — a small sample that has nonetheless been remarkably consistent on one metric: how long the bear market lasts.
Understanding that number won't tell you the exact bottom. Nobody gets that on purpose. But it does give you a window, and a window is enough to build a plan around.
The Four-Year Cycle in Plain Terms
The structure is simple. A bull phase runs a little over 1,000 days as price grinds higher. Then a bear phase runs roughly 370 days as price falls, chops, and eventually forms a base.
Across the three completed cycles, bear markets lasted 410 days, 363–366 days, and 378 days. The average is 371 days with a typical range of 364 to 378 — a spread of only two weeks across three separate cycles.
Peaks and troughs are what anchor those counts. Each cycle's high was followed by a decline, a bottom, and a new expansion. The mechanics behind how bull and bear regimes alternate in crypto markets matter more than the calendar dates themselves, because the regime is what dictates how you should be sizing positions.
Applying the Average to the Current Cycle
The most recent cycle peak landed on October 6, 2025, at roughly $126,200. Add 371 days and you get a projected bottom around October 12, 2026, with the range running from about October 5 to October 19.
By mid-2026 that puts the market roughly 289 days into the bear — close to 80% of the way through, with about 75 days remaining if the pattern repeats.
Price during that stretch sat near $66,000 after a cycle low around $60,000. That's a 52% drawdown from the high, which is shallow by historical standards.
How Deep Do Bitcoin Bear Markets Usually Go?
Here's where the current cycle looks different. Previous bear markets bottomed 87%, 84%, and 78% below their respective peaks.
Apply 78% to a $126,200 high and you get roughly $38,000. Apply 70% and you land near $28,000–$38,000. Compared with a 52% drawdown so far, that implies meaningful downside remains — if history repeats exactly.
Two things argue it might not. First, diminishing returns: the upside multiples have compressed from 17x to about 3.5x to roughly 2–2.2x as the asset matured, and drawdown depth has compressed alongside them. Second, the buyer base changed. Spot ETFs let advisors and institutions allocate without managing individual wallets, and corporate treasuries added a demand source that didn't exist in 2014 or 2018.
Halvings also matter less each cycle, while liquidity conditions and interest rates matter more. And because the model is widely known, front-running can pull buying forward and compress the bear phase.
What the 200-Week Moving Average Adds
The 200-week simple moving average is the indicator most investors pull up in a bear market. It rarely comes up during bull runs, but in drawdowns it tends to act as a rough floor where bottoms form.
That's the strongest argument against a $28,000–$38,000 target: such a move would leave price far below the 200-week line, which would be unusual. When two indicators disagree — historical drawdown depth versus moving-average support — the sensible move is to weigh both rather than pick the scarier one. Adding moving averages and momentum indicators to your crypto charts is how you check that yourself rather than taking a headline at face value.
Building a Plan for the Remaining Window
Three approaches cover most situations:
- Lump sum. Fast, simple, fully exposed to further downside.
- Dollar cost averaging. Split your capital across fixed intervals — say $1,000 weekly over ten weeks. You'll buy some highs and some lows and end with an average.
- Ladder bids. Place resting orders at descending levels. Only the ones price reaches will fill.
DCA and ladder bids share one real advantage: they remove emotion. You define the rule once, then execute mechanically instead of staring at a chart wondering whether now is the moment.
Position size matters as much as entry price. Bitcoin, as the largest-cap asset with deep daily liquidity, is generally viewed as the lower-risk, lower-multiple option — most people treat it as a store of value they intend to hold across cycles. If that describes your thesis, a provider like iTrustCapital is worth a look for anyone exploring how to hold Bitcoin in a tax-advantaged retirement account, since multi-year holding periods and tax treatment interact directly.
