Bitcoin is approaching the lower support line of Fidelity’s long-tracked power law model near $56,000 to $58,000, a technical level that has caught every major market bottom since 2015, according to analysis from the firm’s director of global macro Jurrien Timmer.
The power law is a mathematical model that plots Bitcoin’s entire price history on a logarithmic chart bounded by three curves—an upper resistance line, a middle trendline, and a lower support line. Timmer’s latest chart shows the support line sitting near $58,000, while Bitcoin was trading around $62,700 in mid-July, closing in on that historically significant floor.
Timmer calls the current zone an “accumulation zone,” a term referring to a period where long-term holders typically accumulate assets at depressed prices. The model tracks how far Bitcoin trades above or below the power law trendline, and that gap has swung to negative 56%, matching the depths seen at the 2018 and 2022 cycle lows, according to CoinDesk. The bitcoin-to-gold ratio has fallen just as far, to around negative 100%.
Why the Model Matters
The power law framework was first shared as a Reddit post in 2018 by astrophysicist Giovanni Santostasi and has since become one of the most widely followed long-term Bitcoin valuation tools among institutional investors. Research published in 2026 found that Bitcoin’s price history follows an approximate power law relationship with an R² of 0.947 over the 2011–2026 period, suggesting a remarkably consistent mathematical pattern over time.
However, Timmer stops short of calling a bottom at the support line. He notes that speculative capital has already rotated out of Bitcoin into other assets—first into gold, then into semiconductor stocks—and that global money supply growth is slowing. His assessment is that Bitcoin could sit near the support line for months before any reversal, absent a liquidity catalyst to spark renewed buying interest.
The current setup mirrors past cycles: when Bitcoin has touched or approached this support level in previous bear markets, it has historically marked the floor before multi-year rallies. Yet the model itself is backward-looking, relying on historical price patterns rather than predictive guarantees. Timmer’s cautious stance reflects the reality that even historically reliable technical levels don’t move without fresh demand.
