What Is the Bitcoin Rainbow Chart?
The Bitcoin Rainbow Chart plots BTC's full price history on a logarithmic scale, overlaid with colored bands derived from a logarithmic regression. The idea is simple: Bitcoin's long-term price appreciation follows a predictable logarithmic curve, and the colored bands help identify whether price is historically cheap or expensive at any given moment. The chart was popularized by Blockchain Center as a long-term accumulation guide.
The bands range from deep blue (Fire Sale) at the bottom — historically the best buying opportunities — up through green accumulation zones, yellow hold zones, and into orange/red FOMO and bubble territory at the top. The key insight: Bitcoin has historically spent time in each zone before moving to the next cycle. Buying in the blue or green zones has historically produced exceptional long-term returns.
Use this alongside the Fear & Greed Index and DCA Calculator to build a disciplined, data-driven Bitcoin accumulation strategy. The rainbow chart is a heuristic — not a guarantee — and should never be the sole basis for financial decisions.
