Select a coin
Each coin uses daily USD prices from its first locally cached 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 cached day is above the fitted value near inception. That is a trend classification, not investment advice.
Data model
Local-first market research
cryptorainbowcharts.com ranks assets from the cached CoinGecko market-cap snapshot and reads daily USD history from local JSON files. Full histories are primarily sourced from CryptoCompare, with sparse assets falling back to CoinGecko public history.
Product stance
Signal, not advice
Rainbow bands are a historical visualization model. They can help compare market structure across assets, but they do not predict prices and should not be treated as financial advice.
