Bitcoin booms on a four-year beat. Each boom is smaller than the last.
Before extrapolating anything, measure what's actually there. Bitcoin has run four full boom-and-bust cycles and is partway through a fifth. Around its long-run trend — a smooth path that has tracked sixteen years of price across a thousand-fold climb — price swings far above at each top and back below at each bottom.
Two things jump out. The rhythm's length barely moves: the mature cycles run about four years top to top. But the height of each boom keeps collapsing. It is not the beat that's changing — it's how high each one reaches.

Don't forecast the price. Forecast the pattern.
Here is the centerpiece. Instead of guessing a price, model how the cycle itself is changing — then carry that forward. Two regularities do the work: each boom comes in at about two-thirds the size of the one before (a clean, steady fade), and the tops stay near four years apart.
Run both forward and a price path appears. The next top (~2029) lands near $288K, the one after (~2033) near $540K, and the path reaches roughly $860K by the end of 2036. Seductive — but read the next panel before you believe it.
meta_model_projection
Eight ways to run the cycle forward. They mostly agree — except on one thing.
One model is a single opinion. So we ran the cycle forward eight different ways — a hand-fit fading wave, a popular off-the-shelf forecaster, a self-fading wave, a flexible recurring rhythm, a bubble-timing model, a deep neural net, and a deliberate strawman. Each makes a different bet about how the future rhymes with the past.
What's striking is where they split. Almost all of their disagreement, ten years out, comes down to the one question from Part 2: does the boom keep shrinking, or not?

Has guessing the next top ever actually worked?
A forecast that can't be tested is just a story. So we replayed history honestly: stand at each past top, use only the data available then, predict the next top — and compare it to what really happened. Both methods get a turn: "the boom repeats at full size," and "the boom keeps shrinking."
The verdict is uncomfortable for anyone selling a price target.
cycle_backtest
A pattern worth watching. Not a price you can trust.
This is not advice to buy or sell, and it is not a price target. It's a map of what the cycle data supports as a scenario — and, just as important, how little of it survives an honest stress test.
If the four-year rhythm and its steady fade both continue, the next cycle tops somewhere in the mid-six-figures — the fading models cluster there. That's a scenario, not a target.
Almost the entire forecast reduces to one question: how fast does the boom fade? Most fading models land between about $450K and $860K by 2036, though the slowest-fading wave runs to ~$1.7M; freeze the booms entirely and it reaches ~$1.95M.
Replayed against history, 'the boom repeats' overshot the next top about four times, every time. The shrinking version came far closer — but on only two real tests.
Mid-six-figures next cycle, fading thereafter — held loosely. This is a thought experiment about a pattern, not a price prediction, and certainly not advice.
- —Bitcoin has only ever completed three or four cycles. You cannot validate a ten-year cycle forecast on that — there is almost nothing to test it against.
- —Every model here assumes the past rhythm continues. Regular patterns break; a trend that has held for sixteen years carries no guarantee for the next ten.
- —"The cycle repeats" is the single most over-confident claim in crypto. The backtest shows why: the repeat-at-full-size assumption overshot the next top every time.
- —The price paths are extrapolations, not validated forecasts. The shaded bands describe faster-vs-slower fades, not the true odds of any outcome.
- —Descriptive, not predictive. These models describe a pattern in what already happened; they don't tell you what Bitcoin will do next, 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 four times in this dataset. A repeating cycle is an assumption, not a fact.
