Compare crypto rainbow charts
Crypto Rainbow Charts puts daily cryptocurrency prices in historical context. Each asset has its own fitted power-law trend and colored bands, with downloadable observations and an explanation of the calculations.
| Chart | Daily price (USD) | Model band | Observation (UTC) |
|---|---|---|---|
| Bitcoin Rainbow Chart | $81,875.26 | Warm | |
| Ethereum Rainbow Chart | $2,405.92 | Still Cheap | |
| Solana Rainbow Chart | $104.98 | Still Cheap | |
| XRP Rainbow Chart | $1.30 | Fair Value | |
| Dogecoin Rainbow Chart | $0.0797 | Fair Value |
What is a crypto rainbow chart?
A rainbow chart places a cryptocurrency's historical price alongside colored bands around a fitted trend. It helps visualize how far prices sit above or below that trend. This site's bands use each asset's daily USD history and log-price residuals; they are not the same model as every other Bitcoin rainbow chart.
How should I compare the colors?
Lower bands describe prices below an asset's fitted trend; upper bands describe prices above it. Compare each coin with its own history. The same color across Bitcoin, Ethereum, and Solana does not imply the same risk or expected return. Changing the band width also changes the labels.
Can rainbow charts predict prices?
No chart guarantees a future price. Full-history fits change as new observations arrive, and short histories can give unstable results. Our forecast evaluation separates training observations from later prices and compares forecasts with an unchanged-price baseline.
Check each chart's observation date and data sources before interpreting its bands. These charts are exploratory research, not investment advice.

How to Read the Rainbow Chart
Lower bands generally represent historically depressed prices, while upper bands represent periods where market sentiment has become more speculative.
Limitations
Rainbow charts are visual valuation frameworks, not guaranteed forecasts or trading signals.
The levels describe how far the current price sits above or below the fitted long-term trend in volatility-adjusted log space. Lower bands indicate prices sitting well below trend, while higher bands indicate prices stretched above trend.
Fire Sale
Deeply below the fitted trend; historically the coldest
valuation zone.
Accumulate
Below trend with a wider margin of pessimism than normal.
Still Cheap
Modestly below trend; price remains on the discounted side of
the model.
Fair Value
Near the fitted trend; neither unusually cheap nor unusually
stretched.
Warm
Above trend, showing early momentum without reaching extreme
territory.
FOMO
Meaningfully above trend; optimism is becoming a major part of
the move.
Overheated
Far above trend; risk of a sharp mean-reversion move is
elevated.
Bubble
Extreme upside deviation from trend; the model's hottest
valuation zone.
These labels are descriptive model zones, not buy or sell signals. The rainbow width control changes how wide the zones are, so the same asset can move between levels as the width is adjusted.
Each coin uses daily USD prices from its first available
observation. The chart maps time and price through natural logs,
then fits a power-law trend:
ln(price) = a + b * ln(days_since_inception). In
regular price space that becomes price = e^a * days^b.
The rainbow bands are parallel curves around that fitted trend.
After fitting, cryptorainbowcharts.com computes each day's log
residual
ln(actual_price) - ln(model_price), measures its
standard deviation sigma, and draws bands at
model_price * e^(k * sigma * band_width) for several
k values below and above the trend.
A coin is highlighted as positive since inception when the fitted
exponent b is above zero and the fitted value at the
latest chart day is above the fitted value near inception. That is a
trend classification, not investment advice.
