The Bitcoin rainbow chart has become one of the most iconic visual tools in the cryptocurrency space, offering a colorful and intuitive way to assess Bitcoin’s (BTC) long-term valuation. While not a guaranteed predictor of price movements, it provides valuable context for investors trying to navigate the volatile crypto market. This guide breaks down what the Bitcoin rainbow chart is, how it works, its strengths and limitations, and how to use it effectively alongside other analytical tools.
Understanding the Bitcoin Rainbow Chart
The Bitcoin rainbow chart is a technical analysis tool that visualizes BTC’s historical price movements using a series of colored bands. Each color represents a different market sentiment phase—ranging from extreme undervaluation to speculative overvaluation. By plotting Bitcoin’s price on a logarithmic scale and overlaying color-coded trend lines, the chart helps investors gauge whether BTC is currently cheap, fairly valued, or overpriced based on past cycles.
This model does not rely on real-time fundamentals but instead uses historical price data to project potential support and resistance zones. It's particularly useful for long-term investors who want to avoid emotional trading decisions during market euphoria or panic.

The Origins of the Bitcoin Rainbow Chart
The original Bitcoin rainbow chart emerged in 2014 as a meme created by a Reddit user known as “azop.” It started as a simple logarithmic price chart with straight colored lines—each representing a different valuation tier. At the time, it was more of a humorous take on BTC’s wild price swings than a serious analytical tool.
In 2019, a user named Rohmeo refined the concept by introducing Bitcoin Rainbow Chart V2, which featured curved bands based on a logarithmic regression formula. This version was inspired by an earlier BitcoinTalk post from user “trolololo,” who applied regression analysis to BTC’s price history. The updated model smoothed out price volatility and offered a more data-driven approach to identifying long-term trends.
Today, both versions are available on platforms like BlockchainCenter.net and continue to be widely shared across crypto communities.
How to Read and Use the Bitcoin Rainbow Chart
While the rainbow chart shouldn’t be used in isolation, it can serve as a helpful reference when combined with other indicators. Here’s a step-by-step approach:
1. Identify the Current Price Band
Begin by locating where Bitcoin’s current price sits within the color spectrum. Most interactive versions of the chart allow you to hover over the price line to see exact values and corresponding colors. This gives you an immediate sense of market sentiment.
2. Interpret the Color Zones
Each color band reflects a specific valuation level and investor behavior:
- Deep Blue ("Basically a Fire Sale"): Strongly undervalued—historically seen at cycle lows.
- Cyan ("Buy! Buy! Buy!"): Clearly undervalued—often marks early bull run entries.
- Green ("Accumulate"): Moderately undervalued—strategic buying zone.
- Light Green ("Still Cheap"): Slightly undervalued—good for averaging in.
- Yellow ("HODL!"): Fairly valued—typical of mid-cycle stability.
- Orange ("Is This a Bubble?"): Slightly overvalued—caution advised.
- Light Red ("FOMO Onset"): Possibly overvalued—sign of growing speculation.
- Red ("SELL!"): Highly overvalued—common near all-time highs.
- Dark Red ("Maximum Bubble Territory"): Extremely overvalued—historically precedes corrections.
These labels are informal but reflect common trader psychology during different phases.
3. Analyze Historical Patterns
Look at how Bitcoin has behaved in similar zones in previous cycles. For example, every time BTC entered the deep blue zone, it eventually rebounded into a new bull market. Conversely, prolonged stays in the red zones were often followed by significant pullbacks.
Understanding these patterns helps contextualize current market conditions and avoid panic or greed-driven decisions.
4. Combine with Other Indicators
For more reliable insights, pair the rainbow chart with additional analysis methods:
- Trading Volume: High volume during breakout phases confirms strong market interest.
- Technical Indicators: Tools like moving averages, RSI (Relative Strength Index), and MACD help identify momentum shifts and potential reversals.
- Macroeconomic Factors: Consider broader economic conditions such as interest rates, inflation, and global liquidity—these influence risk appetite and capital flows into crypto.

Does the Bitcoin Rainbow Chart Work?
The effectiveness of the Bitcoin rainbow chart is debated among analysts. While it has successfully highlighted major turning points in past cycles, it's important to understand its underlying assumptions and limitations.
Historical Data Reliance
The chart is built entirely on past performance. While history often rhymes in financial markets, it doesn’t always repeat exactly. Structural changes—like institutional adoption, regulatory developments, or macroeconomic shifts—can alter BTC’s price dynamics in ways the model doesn't account for.
Logarithmic Regression Assumptions
The curved bands in V2 are derived from logarithmic regression, which assumes exponential growth over time. While this fits Bitcoin’s halving-driven scarcity model reasonably well, deviations can occur due to black swan events or sudden shifts in market structure.
Subjectivity of Color Bands
The placement and width of color zones involve subjective judgment. There’s no universal standard for defining “undervalued” or “overvalued,” and adjustments (like adding a purple band in early versions when prices fell below expected lows) show that models evolve post-hoc.
Despite these caveats, the rainbow chart remains popular because it simplifies complex price behavior into an easily digestible format.
Advantages of the Bitcoin Rainbow Chart
- Visual Simplicity: Offers a clear, at-a-glance view of long-term valuation trends.
- Emotional Discipline: Helps investors resist FOMO during bubbles and avoid panic selling during dips.
- Historical Context: Reinforces cyclical nature of Bitcoin markets, encouraging patience and strategic planning.
Limitations to Keep in Mind
- Backward-Looking: Cannot anticipate new market fundamentals or external shocks.
- Static Model: Doesn’t adapt dynamically to changing conditions without manual recalibration.
- Over-Simplification Risk: May lead to complacency if used without deeper analysis.
Are There Rainbow Charts for Other Cryptocurrencies?
Yes—the concept has been extended to other major digital assets like Ethereum (ETH). Ethereum rainbow charts follow the same principle: using historical price data and logarithmic scaling to identify valuation zones. However, given ETH’s different issuance model and ecosystem dynamics, its cycles may not mirror Bitcoin’s exactly.
Other altcoins have also seen fan-made rainbow charts, though their reliability decreases with lower market maturity and liquidity.
Frequently Asked Questions (FAQ)
Q: Can the Bitcoin rainbow chart predict exact price targets?
A: No. It shows historical valuation ranges, not precise future prices. Use it as a guide, not a forecasting tool.
Q: Should I buy or sell based solely on the rainbow chart?
A: Not recommended. Always combine it with volume analysis, technical indicators, and macro trends for better decision-making.
Q: Why are some versions of the chart curved while others are straight?
A: Straight bands (V1) are linear on a log scale; curved bands (V2) use logarithmic regression for smoother trend fitting.
Q: What happens when Bitcoin moves outside the color bands?
A: This has occurred before—such as dropping below the blue zone during crashes or surging beyond red zones in manias. It signals extreme market conditions and may require model updates.
Q: Is the rainbow chart still relevant in mature markets?
A: Yes, especially for long-term holders. Its value lies in illustrating cycles and managing emotions—not generating short-term trades.
Q: How often should I check the rainbow chart?
A: Weekly or monthly reviews are sufficient. It's designed for long-term perspective, not day-to-day monitoring.

Final Thoughts
The Bitcoin rainbow chart is more than just a colorful meme—it’s a powerful visualization tool that captures the emotional rollercoaster of cryptocurrency investing. By mapping historical price behavior across intuitive color zones, it helps investors stay grounded during periods of extreme fear or greed.
However, no single indicator tells the whole story. To maximize its utility, integrate the rainbow chart into a broader analytical framework that includes volume trends, technical signals, and macroeconomic awareness. When used wisely, it becomes not just a chart—but a compass for navigating Bitcoin’s unpredictable journey.
