Where Bitcoin's On-Chain Cost Basis Lines Say the Next Bottom Could Sit
Three on-chain cost-basis lines currently sit 15-23% below spot. That gap matters because, across the last three complete cycles, the bottom broke below all three every single time.
At $64,633 (as of 2026-07-26), the three lines are Realised Price at $52,868, Cointime Price at $51,963, and Long-Term Holder (LTH) Cost Basis at $50,012. None of them have been touched yet this cycle.
What these three lines measure
Realised Price, Cointime Price, and LTH Cost Basis are all on-chain cost-basis models — different methodologies for estimating the market's average holding cost. Historically, the zone where these three lines cluster together is where bear-market buying concentrates, and it's also where the real bottom of past cycles has tended to form.
How the last three cycles broke through them
| Cycle bottom | Bottom price | Realised Price | Cointime Price | LTH Cost Basis | Overshoot past Realised Price |
|---|---|---|---|---|---|
| 2015-01-14 | $168.99 | $310.75 | $253.52 | $300.94 | 45.6% |
| 2018-12-15 | $3,190.11 | $4,611.98 | $4,159.85 | $4,414.80 | 30.8% |
| 2022-11-21 | $15,611.74 | $20,269.99 | $17,407.77 | $20,589.55 | 23.0% |
At every one of those three bottoms, price broke below all three lines. And the overshoot — how much further price kept dropping after breaking Realised Price — has been shrinking cycle over cycle: 45.6% → 30.8% → 23.0%. Breaking all three lines together isn't new this cycle; it's what genuine cycle bottoms have historically done. But the depth of the overshoot has gotten shallower each time.
Where things stand now
At the current price of $64,633, none of the three lines — $52,868, $51,963, $50,012 — have been touched. A local low of $58,051 on June 25 came within 9.8% of the highest of the three (Realised Price), which tells us this pullback hasn't yet reached the depth that historical bottoms typically go to.
Scenario matrix: the next 3 months (through roughly end of October 2026)
| Scenario | Target price | Drawdown from current | Breaks all three lines? |
|---|---|---|---|
| Optimistic: holds above the prior low | Around $58,000 | -10.3% | No |
| Base case: tests Realised Price | ~$52,868 | -18.2% | Breaks Realised Price |
| Bearish: all three lines break | ~$50,012 | -22.6% | Breaks all three |
| Tail case: matches historical overshoot | $40,700-$44,900 range | -31% to -37% | All three broken, 15-23% past Realised Price |
The base and bearish cases are the two this analysis actually wants to emphasize — the odds of breaking Realised Price aren't low, and it's worth mentally preparing for a break of LTH Cost Basis too. The tail case is given as a range rather than a single number: the low end uses 2022's 23% overshoot, the high end extrapolates the "overshoot shrinking each cycle" trend (45.6% → 30.8% → 23.0%, which if it continues would land around 15%). That tail scenario is an extreme reference point, not the base prediction, and it comes with no defined time window.
How this connects to the 500/500 rule
The 500/500 rule gives a time window: November 9-16, 2026. This gives a price range: $50,012 to $52,868. The two frameworks answer different questions — one is "when," the other is "how deep" — not the same logic restated twice. If this downside move actually happens with the timing landing near the November window and the price landing near this cost-basis range, that would count as a reasonably complete convergence. But that's not guaranteed to happen — both lines still carry their own independent uncertainty.
Where this breaks down
- All three lines drift upward over time (LTH Cost Basis especially, as more supply shifts to long-term holding), so this "target range" is an estimate for the next 3 months specifically, not a fixed price level.
- Only one historical sample (2022) is directly comparable to the current macro environment — whether this cycle repeats the same depth and overshoot isn't something to treat as a foregone conclusion.
- This framework answers "how far might price go," not "on exactly what date." The actual pacing still depends on market structure at the time.
