🌈 Bitcoin Rainbow Chart

The Rainbow Chart will not tell you where Bitcoin is going tomorrow. What it will tell you is whether today is a historically cheap, fair, or expensive time to be buying Bitcoin — and that is often more valuable. I have used this chart since 2017 as a sanity check against my own FOMO. When the orange and red bands flash, I slow down new purchases. When the blue and purple bands appear, I buy more aggressively. It is not a trading signal. It is perspective — and in this market, perspective is rare.

What the Rainbow Chart Actually Is

The Rainbow Chart is a logarithmic regression curve fitted to Bitcoin price history since approximately 2012, with colored bands representing statistical deviations from that central regression line. The underlying model assumes Bitcoin long-term price growth follows a power law — each successive bull market cycle peaks at a lower multiple than the previous one, but at a higher absolute price. It was created by community analyst Über Holger and popularized by Blockchaincenter.net. Crucially, it is not a prediction model. It is a valuation framework that contextualizes where current price sits relative to the long-term growth trend.

The 9 Rainbow Chart Bands

From bottom to top, the nine bands represent escalating levels of valuation relative to the logarithmic baseline:

Historical Rainbow Chart Accuracy

The chart has a genuine track record when used as a macro perspective tool rather than a short-term signal. The 2015 bottom at $150 registered in the dark blue fire sale band — arguably one of the best Bitcoin buying opportunities ever. The 2018 bottom at $3,150 hit blue-to-dark-blue territory again. The November 2021 peak at $68,789 flashed dark red maximum bubble territory — traders who heeded that signal avoided the subsequent 77% drawdown to $15,500. The 2022 bottom at $15,599 dropped back into the blue-cyan accumulation zone. At approximately $94,000 in 2026, Bitcoin sits in the green-to-yellow band range — fairly valued by historical logarithmic standards, neither a fire sale nor a bubble.

How to Use the Rainbow Chart

The Rainbow Chart is a long-term perspective tool only — it is essentially useless for short-term trading and was never designed for that purpose. The practical approach: in red and dark red zones, consider taking partial profits and avoid deploying new capital aggressively. In blue and purple zones, these are historically optimal accumulation periods worth dollar-cost averaging heavily. In the green middle bands, steady DCA with no need to dramatically change strategy. The chart should never be your only signal. Combine it with on-chain data (MVRV ratio, SOPR, exchange flows), market cycle indicators (Pi Cycle Top, NUPL), and your own assessment of macro conditions.
