Bitcoin Has Been Below Its Power-Law Floor for 56 Days — Is That Normal?
Bitcoin is trading below a line it almost never trades below. At $63,696 (as of 2026-07-28), price sits under the power-law model's floor price — the Q5 quantile line, currently at $69,167 — and has stayed there for 56 days running, starting June 3. The power-law model itself just fits Bitcoin's price history to a long-run growth trend over time; the floor is the low edge of that fitted band.
That's worth a second look for one reason: across the three comparable historical cycles, this has only happened once before.
What the floor price is
The Q5 quantile line is a statistical lower bound the power-law model derives from Bitcoin's historical price distribution — the level where, historically, price has rarely traded below. Breaking it isn't a standard feature of every bear market; it's a rare event.
Checking three historical cycles
| Cycle low | Bottom price | Floor price at the time | Broken? | Undervaluation reading |
|---|---|---|---|---|
| 2015-01-14 | $172.2 | $142.2 | No | 0.557 |
| 2018-12-15 | $3,237.1 | $2,578.9 | No | 0.577 |
| 2022-11-21 | $15,797.5 | $17,734.9 | Yes | 0.410 |
Only 2022 actually broke the line among these three comparable cycles. The 2015 cycle low didn't break it either — the actual break came later, in the August-October 2015 retest (bottoming at $211.0 on 2015-08-24, against a $247.9 floor at the time, lasting roughly 68-70 days). The 2018-2019 bear market — an 84% drawdown from $20K — never broke it at all.
Breaking the floor price isn't something that happens every cycle. Historically it's closer to once in three.
Where things stand now
Price has been running below the floor price for 56 days — one of the longer durations among the handful of historical breaks (compare: 62 days in 2022, roughly 68-70 days in the August-October 2015 retest, similar order of magnitude). The low point during this stretch was $58,524 on June 30; price has since bounced back to $63,696, about 8.6% below the floor line.
The current undervaluation reading — a 0-to-1 score measuring how far price sits below the power-law model's fitted trend line, where lower means more undervalued — is 0.4235, close to 2022's cycle-low reading of 0.410. That puts it in the historically undervalued range.
Is this bounce the bottom? What 2022 did
| Date | Price |
|---|---|
| 2022-11-21 (cycle low) | $15,797.5 |
| 2022-11-22 | $16,178.9 |
| 2022-11-23 | $16,622.3 (bounce high, +5.2%) |
| 2022-11-24 to 27 | $16,450-$16,589 (mild pullback) |
| 2022-11-28 | $16,221.6 |
In 2022, price bounced 5.2% off the low, pulled back mildly over the following week, and never retested the original low. That wasn't a full retest — just a normal, low-volume consolidation after a bounce. If this cycle follows the same rhythm, the odds of $58,524 getting retested aren't high. But that's a sample size of one, not a rule to bank on.
Where this breaks down
- The floor price itself drifts slowly over time (the model is derived from a long-run pricing trend, not a fixed number), so the specific figures here only apply as of 2026-07-28's data.
- Of the historical breaks, only 2022 is a clean single-peak bear-market bottom. The 2015 break happened during a second retest rather than the cycle's first bottom — the market structure isn't identical between the two samples, so they shouldn't be extrapolated into one rule without caveat.
- This framework answers "is the current price statistically rare by historical standards," not "on exactly what date does it bottom." The actual pacing still depends on how price and the undervaluation reading actually move from here.
Rare signals are worth taking seriously. Ordinary noise isn't.
