₿ Model by Giovanni Santostasi, PhD
Bitcoin has followed the same mathematical curve for 15 years. No model is perfect — but no model has survived this long either.

Most price models fail because they mistake correlation for causation. Giovanni Santostasi's Power Law is different. It is grounded in a structural observation about how Bitcoin adoption grows — the same mathematical pattern that governs cities, biological organisms, the internet, and virtually every complex network that humans have ever built.
Power laws appear throughout nature and society. The key insight is that as Bitcoin scales, adoption grows not linearly but by a constant exponent relative to time since the Genesis Block. This relationship has persisted across four complete market cycles, including crashes of 80% or more.
"Bitcoin is more similar to a city and an organism than a financial asset. It is ruled by power laws."

The corridor defines two historical bounds. The upper resistance line represents the ceiling of bull market peaks. The lower support line represents the floor — every major bear market bottom has approached or touched this line before recovering. Between the two corridors, the midline represents "fair value" at any moment in time.
What makes the model extraordinary is not that it predicted specific prices — it did not. What it predicted is the range. Bitcoin has never spent a meaningful period of time outside the corridor. Every time it approached the upper bound, it eventually pulled back. Every time it collapsed toward the lower bound, it eventually recovered.
| Cycle Peak | Lower Support | Fair Value | Upper Resistance | Actual High |
|---|---|---|---|---|
| 2013 | $27 | $109 | $432 | $1,150 † |
| 2017 | $1,100 | $3,500 | $13,900 | $19,700 † |
| 2021 | $6,900 | $27,500 | $109,500 | $69,000 ✓ |
| 2026 (now) | ~$-- | ~$-- | ~$-- | In Progress |
| 2030 | ~$122K | ~$487K | ~$1.9M | Projected |
† Early cycles (2013, 2017) briefly exceeded the upper band as the model calibrated with fewer data points. Post-2020, adherence has tightened significantly.
Every bear market felt like the end. Every bull market felt like madness. The corridor just kept rising. Patience is the strategy.
