How to Read This Chart

The model fits a power-law (log-log linear) regression to Bitcoin's entire price history. The center line represents "fair value" according to this model.

The bands are spaced at intervals of the residual standard deviation. Prices in the blue zone are historically cheap; prices in the red zone indicate overheating.

Limitations: Past performance does not guarantee future results. The model assumes BTC will continue its historical power-law trajectory, which may not hold indefinitely.

Best used as one signal among many. Combine with on-chain metrics, market structure analysis, and macro indicators for a fuller picture.
