What Is the Bitcoin Rainbow Chart and How to Use It?

Imagine looking at a weather map rather than a price chart: blue areas signal cold, while red areas indicate heat. The Bitcoin Rainbow Chart works in much the same way. It overlays Bitcoin’s historical price trends with the colors of the rainbow, with each shade representing a different stage of the market cycle—from panic and undervaluation to optimism and euphoria.

The Bitcoin Rainbow Chart is not a forecasting tool. Instead, it guides long-term investors by helping them assess where the current Bitcoin price stands relative to its historical trends. It can’t tell you how BTC will trade tomorrow, but it can provide a broader perspective—something particularly valuable in the highly volatile crypto market, where short-term price action can easily obscure the bigger picture.

The Rainbow Chart is not meant to replace tools such as the Stock-to-Flow model or the Fear and Greed Index. Rather, it complements them. While other indicators offer different perspectives on Bitcoin’s valuation and market sentiment, the Rainbow Chart highlights how far the current price has moved from its long-term trend. Blue shades suggest a cooled market, while red shades signal increasingly overheated market conditions.

This article explains how the Bitcoin Rainbow Chart actually works and how investors can use it to trade Bitcoin successfully.

Major Takeaways

• The Bitcoin Rainbow Indicator uses logarithmic regression to illustrate Bitcoin’s long-term price trend.

• Reddit user Azop created the tool in 2014 as a meme, with an updated V2 version released in 2019.

• The chart consists of nine colored bands, ranging from Fire Sale (Dark Blue) to Maximum Bubble Territory (Dark Red).

• The BTC Rainbow Chart is designed for long-term market assessment rather than short-term price forecasting.

• It shows how far the current Bitcoin price has deviated from its long-term logarithmic growth curve.

• The indicator does not guarantee future results and should therefore be used alongside other tools, such as RSI, MACD, and the Fear and Greed Index.

• The Bitcoin Rainbow Chart helps investors identify different market phases, from accumulation and undervaluation to the Maximum Bubble zone.

• Unlike many other models, the BTC Rainbow does not predict specific price levels; it provides a probabilistic estimate of fair value.

Bitcoin Rainbow Chart Explained

What is the Bitcoin Rainbow Chart? It is a color-coded representation of BTC’s price, divided into nine bands. Each band corresponds to a different phase of the market cycle: blue indicates relatively low prices, while red signals elevated valuations. The green, yellow, and orange zones lie between these extremes, with each color providing a visual guide to the prevailing market conditions.

Imagine a swimming pool: the blue area is shallow, where you can stand on the bottom, while the red area is deep, where you have to swim. The Bitcoin Rainbow Price Chart works in much the same way. The lowest band represents low price levels, while the upper bands indicate increasingly high valuations.

The chart is plotted on a logarithmic scale. This scale compresses large values, making it easier to compare relative price changes across different periods. Bitcoin has risen from just a few dollars to tens of thousands, so on a linear chart, its early price movements are virtually indistinguishable. A log scale makes the entire price history more visible. That is why the BTC Rainbow Chart is useful for assessing the long-term trend and determining where the price stands relative to its historical trajectory.

This is especially important in the emotionally charged crypto market. When Bitcoin’s price drops sharply, panic can set in; when it rises rapidly, euphoria takes over. The Rainbow Chart helps filter out short-term noise and focus on the bigger picture. Historically, periods when the price has deviated significantly from its long-term trajectory have often been followed by moves in the opposite direction.

Who Created the Bitcoin Rainbow Chart?

In 2014, when Bitcoin was in a bear market following the 2013 boom, Reddit user Azop posted “Actual Bitcoin Price vs. Trendline Deviance,” featuring the first version of the chart: five colored bands plotted on a logarithmic scale. It was simple, visual, and had a touch of humor.

Later, a BitcoinTalk forum user going by the username trolololo refined the concept by applying logarithmic regression. This laid the foundation for what would become the modern chart.

In 2019, an enthusiast named Rohmeo updated the model, introducing a curved rainbow with nine colored bands. This became the Bitcoin Rainbow Chart V2—the new version that laid the foundation for the modern chart. Although Eric Wall is sometimes credited with its creation, several community members developed the model. The original rainbow chart gained popularity thanks to its simplicity and visual clarity.

The Bitcoin Rainbow Chart was created not by Wall Street analysts, but by internet enthusiasts—and the long-term valuation tool went on to gain widespread popularity.

How Does the BTC Rainbow Chart Work?

Bitcoin’s Crypto Rainbow Chart is based on a logarithmic regression model. Logarithmic regression is a mathematical method that lets us plot a curve showing changes in Bitcoin’s price throughout its history. The logarithmic growth curve reflects long-term trends and the gradual slowdown in the growth rate.

How the chart is constructed:

1. The Bitcoin Log Chart uses historical BTC price data from 2009 to the present.

2. A logarithmic regression model is constructed to form the central trend line.

3. Bands are formed around it, reflecting different levels of deviation from the main trajectory.

4. The bands are colored like a rainbow, ranging from blue, corresponding to the lower levels, to red, corresponding to the upper levels.

What is a logarithmic scale? On a standard scale, values increase in equal increments: 1, 2, 3, 4. On a logarithmic scale, they increase by multiples: 1, 10, 100, 1,000. As a result, an increase from $1 to $10 and from $10 to $100 appears the same. This type of scale allows us to compare relative rather than absolute price changes.

The chart does not predict future price movements; rather, it shows how far the current price is above or below the long-term trend.

Notably, the regression model may be recalculated as new data becomes available. For example, the 2019 update changed the curve’s shape, making it flatter at the top. Such adjustments are normal for a statistical model.

Unlike Stock-to-Flow, the Rainbow Chart does not account for the Bitcoin halving. This event reduces the issuance of new bitcoins by cutting the block reward. Instead, the model is based on historical price movements and allows investors to assess the price’s position relative to the long-term trend.

Bitcoin Rainbow Chart Colors: All Nine Bands Explained

The Bitcoin Rainbow Chart includes nine colored bands, each corresponding to a specific market condition and BTC price range. The table below explains what each color means and how to interpret the price level in each zone.

This is not a "buy Bitcoin here, sell there" guide, but rather an indicator of market sentiment. Red zones indicate that the market is relatively overheated, while blue zones suggest that it is cooling off. However, neither zone alone can predict the start of a bear or bull market.

The BTC price rarely reaches extreme zones—the lower blue zone and the upper red zone. For example, in 2022, Bitcoin fell into the blue zone, while at the end of 2020, it moved into the orange zone. Such market phases help track transitions between periods of decline, accumulation, growth, and overheating.

The colored bands are not rigid boundaries: the price may touch them or move beyond them. Therefore, the blue zone does not guarantee a subsequent rise, just as the red zone does not imply a decline. If the current price is within the blue band, the model indicates that Bitcoin is potentially undervalued compared with its long-term trajectory. The red zone, on the other hand, indicates that it is relatively overvalued.

How to Use the BTC Rainbow Chart

The Bitcoin Rainbow Chart is primarily a long-term analysis tool, making it better suited to investors than to scalpers or intraday traders. Using this tool for cryptocurrency trading therefore requires a medium- to long-term approach.

Step 1. Determine Current Position

Open the Bitcoin Rainbow Chart on BlockchainCenter or another website and determine which color band the BTC price is in. Take a screenshot of the chart so you can track changes over time.

Step 2. Assess Market Phase

• Blue and green zones — Bitcoin is relatively cheap compared with its long-term trend. These ranges can be considered potential areas to enter a position or use dollar-cost averaging (DCA).

• Yellow zone — the price is closer to the middle of the model’s range.

• Orange and red zones — Bitcoin is relatively expensive compared with its long-term trend. These price ranges can be considered potential areas to take profits.

Step 3. Compare with Other Indicators

A single indicator provides only a limited view, so use the Rainbow chart in conjunction with other tools:

• RSI indicates overbought and oversold conditions.

• MACD helps assess a trend’s direction and strength.

• Fear and Greed Index reflects market sentiment.

• ETF Flows show capital inflows and outflows.

• Stock-to-Flow provides an alternative valuation of Bitcoin.

Important: Use higher time frames—1D and above.

Step 4. Define Your Investment Horizon

• Short term (days to weeks) — the Rainbow Chart is not very informative, so it is better to use other tools.

• Medium term (months) — it provides general context but does not offer precise signals.

• Long term (years) — it allows you to assess the price’s position in the context of several market cycles.

Step 5. Make Informed Decisions

A price in the blue zone does not necessarily signal an uptrend, just as a price in the red zone does not necessarily suggest a downtrend. The Bitcoin Rainbow Chart is a probabilistic tool that shows how the price has behaved in similar zones in the past. However, past performance does not guarantee future results.

When making investment decisions, always consider market liquidity, the macroeconomic environment, and regulatory risks.

What the Bitcoin Rainbow Chart Cannot Do

The Bitcoin Rainbow Chart is based on historical data, so it has several limitations.

• It does not predict the future. History does not repeat itself exactly, and the model has been adjusted as new data has become available. Moreover, future prices may be influenced by new factors, such as the widespread adoption of Bitcoin or tighter regulation.

• It does not account for fundamental changes. The logarithmic regression model is based on price and time and does not directly account for factors such as institutional investment, ETFs, or regulation. For example, ETF inflows can affect the price, but the chart does not treat them as a separate variable. It also does not account for Bitcoin halvings, which reduce the rate at which new bitcoins are issued.

• It ignores macroeconomic factors. The model does not include Fed interest rates, inflation, or recessions. Therefore, the Rainbow Chart cannot independently assess the impact of macroeconomic conditions on Bitcoin’s price.

• The bands are subject to revision. The model has been updated over time and has acquired new formulas and color ranges. Therefore, the zone boundaries should not be considered fixed.

• It is not suitable for active trading. The Rainbow Chart is designed for long-term analysis and is not well suited to intraday trading or short-term price analysis.

• Colors are guidelines, not guarantees. Zone labels such as “Buy!” are conventional designations, not objective trading signals. The Rainbow Chart is not an investment advice. Instead, view it as one of several indicators for assessing market conditions.

• It does not cover altcoins. The original chart was created for Bitcoin, although similar charts exist for other cryptocurrencies. Bitcoin dominance reflects BTC’s share of total crypto market capitalization, but the Rainbow Chart itself is not designed to analyze altcoins or identify altcoin seasons.

Conclusion

The Bitcoin Rainbow Chart is more of a compass than a navigator: it shows the direction but does not plot the route. Nine colored bands, ranging from “sell-off” to “bubble,” help assess the price’s position within the long-term market cycle. The chart provides context rather than signals for immediate action.

Its main value lies in its long-term perspective. When the market is gripped by panic, the price may be in the blue zone; during periods of euphoria, it may move into the red. The chart allows you to step back from short-term noise and see the bigger picture.

Use the Bitcoin Rainbow Chart as a filter for emotions, but not as the sole basis for decision-making. Cross-reference it with on-chain data and the Fear & Greed Index. To assess capital rotation into altcoins, use the Altcoin Season Index separately. Market sentiment can change faster than the color bands, so the chart should not be considered an investment recommendation.
