Bitcoin Rainbow Chart

What Is the Bitcoin Rainbow Chart?

The Bitcoin Rainbow Chart is a long-term valuation tool that overlays color bands on a logarithmic regression of Bitcoin's price history. It was originally created as a fun way to visualize Bitcoin's growth pattern, but it's become one of the most popular charts in the crypto community because of how well the bands have tracked major market phases.

The chart uses a logarithmic growth curve, which makes sense for Bitcoin since its price appreciation follows a power law, rapid growth early on that slows over time. The rainbow bands represent different sentiment levels, from "Basically a Fire Sale" at the bottom (blue) to "Maximum Bubble" at the top (red).

How to Read the Bands

Each color band represents a different market phase:

• Blue/Indigo ("Basically a Fire Sale" / "BUY!"): Price is well below the long-term trend. Historically, these levels have been excellent buying opportunities. You typically see these during bear market capitulation events.
• Cyan/Green ("Accumulate" / "Still Cheap"): Price is below the regression midpoint. Smart money tends to accumulate here. These periods can last months during bear markets.
• Yellow/Green ("HODL!" / "Is This a Bubble?"): Price is near the regression line. The market is roughly fairly valued by historical standards. Most of Bitcoin's time is spent in this zone.
• Orange/Red ("FOMO Intensifies" / "Sell. Seriously, Sell!" / "Maximum Bubble"): Price is well above the trend. These are the euphoric peak zones where markets tend to overshoot. Every previous cycle top has reached into these bands before correcting.

Is the Rainbow Chart Accurate?

The chart has been remarkably consistent at identifying broad market phases. Bear market bottoms have landed in the blue/cyan bands, and cycle tops have reached into the orange/red bands. That said, it's not a prediction tool. It shows where the current price sits relative to the long-term logarithmic trend, nothing more.

The regression parameters get adjusted over time as more data comes in, which means the bands shift slightly. And there's no guarantee that Bitcoin will continue following a logarithmic curve forever. As the market matures and volatility decreases, the model might become less useful. Use it as one input among many, not as gospel.

Rainbow Chart vs. Stock-to-Flow

Both are long-term Bitcoin valuation models, but they work differently. Stock-to-Flow ties value to Bitcoin's scarcity (supply reduction through halvings), while the Rainbow Chart simply fits a logarithmic curve to historical price data without any economic theory behind it. The Rainbow Chart has actually held up better in recent cycles, partly because it's less rigid in its predictions.
