Bitcoin Rainbow Chart

Log regression bands · Fire sale zone or peak bubble?

What is the Bitcoin Rainbow Chart?

The Bitcoin Rainbow Chart fits a long-term logarithmic regression to price and overlays colored valuation bands — from the blue "fire sale" zone at the bottom to the red "maximum bubble" zone on top. It is the most intuitive long-cycle valuation visual.

How do I use the Bitcoin Rainbow Chart?

Blue/teal bands have historically been accumulation zones for long-term holders, yellow is neutral, and orange-red signals overheating. It best answers "is this expensive on a multi-year horizon" and pairs naturally with adjusting DCA size per band.

What should I watch out for?

The rainbow is a heuristic, not a forecast — its regression parameters drift and have required refitting several times since 2021. Never treat a single band as a precise entry or exit level.
