Bitcoin keeps the same four beats, cycle after cycle.
Forget the price for a moment and just watch the rhythm. Roughly every four years, after the halving cuts new supply, Bitcoin runs through the same four stretches in the same order: a long run-up, a top, a bear, and then a long base before the next run-up. It is the most repeated pattern in the asset's whole history.
The chart below colors Bitcoin's price by where it sat in that clock at every moment — measured purely by how many months had passed since the last halving. Notice the colors line up cycle over cycle. And notice where the line ends: today, about 26 months past the 2024 halving, just after the October-2025 top — in the handoff from the bear to the long base.

The timing of each turn repeats — remarkably.
Here is the part of the cycle that genuinely holds up. Measure, for each cycle, how many months passed from the halving to the top, and from the top to the bottom. Then look at how tightly those spans cluster. The three modern cycles all topped within a few weeks of the same point, and all bottomed within a month and a half of each other.
The top-to-bottom span is the tightest beat of all: 13.3, 12.0, and 12.4 months — three numbers inside a month and a half of each other.

But the price at each turn? That's the weak half.
Knowing when the cycle turns is not the same as knowing the price it turns at. So we ran the same fair, out-of-sample test on the dollar level — and the cycle loses. Using the cycle's shape to guess the price beats a coin-flip that assumes the price just stays put, so it carries some information. But a plain long-run trend line beats it at both horizons.
That is the honest dividing line of this entire report: the cycle tells you the timing, not the magnitude.

So where does the clock point next?
We are about 26 months past the 2024 halving — roughly two-thirds of the way through a typical descent from the top. The clock's sharp half says the next cycle low should land around late-2026 — honestly, somewhere between September 2026 and early 2027. A separate cross-check, using how the bottoms have arrived later each cycle, points to about January 2027 — close enough to reinforce the window.
The weak half is the dollar level. So we draw it as a deliberately wide band, not a target — and then, just as importantly, we show the turn back up the clock expects after the low. This is a down-then-up path, not a one-note bear call.

A reliable clock. An unreliable ruler. Both, honestly.
This is not advice to buy or sell, and the price band is not a target. It's a map of what the cycle can and can't tell you: the timing of the next turn, which genuinely repeats — and the price at that turn, which doesn't. We show both halves, and we keep the small sample loud.
The timing. Each cycle tops ~17–18 months after the halving and bottoms ~12–13 months after that. Out of sample, predicting the top-to-bottom span from earlier cycles missed by about a week — and the October-2025 top validated the template live.
The price. Guessing the dollar level at each turn beats a coin-flip but loses to a plain trend line, and the band is wide. We estimate WHEN, not how much. The dollar level is a guess, not a target.
From ~$62K today, the clock points to the next low around late-2026 (honest band: Sep 2026 → early 2027), then a turn back up into 2027–28. The next top is ~2029–30 — outside any one-to-two-year window.
Wide on purpose: roughly $18K (deep repeat) to $62K (soft cycle / low near), middle near $33K. A range to hold loosely, never a target — the half of this report we trust least.
- —Only three completed cycles back the bottom-timing (four tops). You cannot firmly validate a cycle method on a handful of examples — every number here rests on a tiny sample, and the no-leak test reduces it to one or two truly out-of-sample events.
- —The timing repeats; the price does not. The dollar band is wide by design and, in the back-test, was under-covered — it caught fewer outcomes than it promised. Treat the price scenarios as a guess, not a calibrated forecast.
- —The cycle may be weakening. Drawdowns have shrunk every cycle and this one is the shallowest so far. If the rhythm is fading, the timing edge fades with it — this is an open question the data can't yet settle.
- —A repeating four-year cycle is an assumption, not a law. A pattern that has held for a dozen-plus years carries no guarantee for the next one. Halvings are protocol facts; the price response around them is not.
- —Descriptive, not predictive. This maps a pattern in what already happened and where the clock points next. It is an observation about timing, not a price target, and nothing here is financial advice.
Descriptive research, not financial advice. Bitcoin is volatile and can lose most of its value in a year — as it has in every cycle in this dataset. A repeating cycle is an assumption, not a fact, and the price band is a wide guess, not a target.
