BTC: Power-Law Model — 2019 Calibration
Bitcoin Power-Law Model — 2019 Calibration was $189,636.92 on 7 Nov 2026 (latest daily value).
A modeled USD/BTC price from a published 2019 power-law calibration against days elapsed since 3 January 2009.
Why use it. Provide a fixed, deterministic power-law curve against which observed price can be compared. How to read it. This is a descriptive calibration, not a market observation, fair value, support guarantee, confidence band or forecast; no future projection is shown. Its coefficients were published on 2019-09-03, so earlier points apply them retrospectively. Open or unsealed days are undefined; sealed days fewer than six blocks deep remain provisional. A missing interior day stays a gap without resetting the age clock. Viewport and smoothing choices never reset the fixed calendar origin.
Calculation. Modeled USD/BTC = 10^(-17.01593313) × d^(5.84509376), with fixed coefficients that are not refitted. For the day plotted at D 00:00, d counts elapsed whole days from 2009-01-03 00:00 UTC to that day's ending boundary, so genesis day uses d = 1; this daily-boundary convention is ours. Evaluated as exp(A × ln 10 + B × ln d) with 40 significant digits, half-even. Native daily supply rows from our own validated Bitcoin Core node establish history and finality but do not enter the formula.
