The Bitcoin Rainbow Chart is a long-term valuation framework that places BTC inside colored bands around a trend model. This version adjusts band width for cycle-level volatility, which makes the structure more adaptive when different halving eras are calmer or more unstable than the last.
Current Readings
As of 2026-05-19, Bitcoin is trading at $77,223 versus a model price of $177,598. That puts BTC at -56.52% relative to the fair-value curve and in the BUY! zone.
The current volatility-adjusted z-score is -1.762, while the cycle volatility ratio is 0.5x. The volatility-adjusted z-score is in a deeply discounted zone, suggesting Bitcoin is trading well below the fair-value curve relative to cycle volatility.
What is the Bitcoin Rainbow Chart?
The classic Bitcoin Rainbow Chart takes a long-term growth model and wraps it in multiple colored valuation bands. Those bands give investors a fast visual answer to a simple question: is Bitcoin trading in historically cheap territory, somewhere in the middle of the cycle, or in a regime that looks increasingly overheated?
That basic framing is useful because it converts a raw price series into a valuation map. Instead of looking only at today's BTC price, the chart helps position Bitcoin relative to its longer-duration trend.
How this volatility-adjusted version differs from the original
Classic rainbow models are often based on logarithmic growth alone. That can work well as a visual heuristic, but it assumes the same effective band width across very different Bitcoin cycles. In practice, some halving eras are far more volatile than others.
The model first fits a log-age regression for Bitcoin price, then measures cycle-level return volatility and rescales residual width with a volatility ratio. The result is a rainbow whose spread responds to cycle conditions rather than staying mechanically fixed.
That makes this page better suited to cross-cycle comparison. When volatility compresses, the rainbow can tighten. When volatility expands, the model can widen the expected valuation envelope instead of pretending the distribution is unchanged.
How to read the rainbow zones
The lower part of the structure — Basically a Fire Sale, BUY!, and Accumulate — is designed to capture stress, washout, and high-conviction long-term value zones. The middle of the structure — Still cheap and HODL! — marks healthier trend territory where Bitcoin is no longer deeply discounted but is not yet extremely stretched.
The upper part of the structure — Is this a bubble?, FOMO intensifies, and Sell. Seriously, SELL! — is where price moves further above the fair-value curve and upside becomes progressively harder to justify with normalized cycle context. Above a z-score of 2.0, the model labels the regime Maximum Bubble Territory.
What band is Bitcoin in right now?
Right now the model places Bitcoin in BUY!. That assessment is derived directly from the current volatility-adjusted z-score, not from hardcoded commentary. In practical terms, the model says Bitcoin is trading -56.52% relative to fair value on a cycle-normalized basis.
The current zone updates automatically as the model and price data change.
How traders and long-term investors use the chart
Long-term investors use rainbow models to frame accumulation and risk-reduction zones across a full cycle. Traders use them less as a prediction engine and more as a regime filter: lower bands can justify patience and accumulation, mid bands can frame trend continuation, and upper bands can signal that reward-to-risk is becoming less favorable.
The best use case is context, not certainty. This page works especially well when paired with other valuation and holder-behavior tools like Realized Price, Realized Price Bands, MVRV, and NUPL.
Limitations of the Rainbow Chart
No rainbow model is a short-term timing tool. It does not guarantee exact tops, exact bottoms, or immediate reversals. Model risk exists, parameter risk exists, and Bitcoin can remain overvalued or undervalued for longer than a single signal implies.
This page is best treated as a long-horizon valuation dashboard, not financial advice. It helps frame probabilities and context, not certainty.
