A peer-reviewed study published in Elsevier's journal Nonlinear Science claims Bitcoin's long-term price follows a power law trend tied to network adoption. Physicist Giovanni Santostasi and co-author Stephen Perrenod analyzed 5,696 daily prices from July 2010 to February 2026, finding that a single power law curve explains approximately 96% of Bitcoin's long-run price variation. The model attributes growth to two forces: new user adoption in accelerating waves (similar to a 1989 AIDS epidemic study) and Metcalfe's Law, where network value squares with user count. The prediction lands within 1.6% of actual growth rates. Critics earlier dismissed the model as curve fitting, but the authors claim to have closed the gap by deriving growth rate mathematically rather than fitting data. The paper also specifies five measurable conditions that would break the trend, such as price falling 3 standard deviations below the trend for over a year (F1). The study ends in February 2026, leaving the current bear market as the first live test. Bitcoin trades near $60,642, 43% lower year-over-year. The model has survived all previous bear markets within normal swing ranges. However, the authors avoid price targets, and the trend does not guarantee future returns.
