BTC Power Law Rainbow: $79,676.63
Nine coloured bands built around Bitcoin's long-term growth curve, with the whole corridor projected forward to 2030. Cold blue near the bottom has been bargain territory; hot red near the top has marked bubbles.
The same fitted growth curve as the Power Law chart, surrounded by nine coloured bands at even distances **above** and **below** it. Unlike the classic Rainbow, these bands are extended forward to 2030.
Read the colour sitting under the price. For example, the price in the second-lowest band means it is far **below** its long-term growth curve — every past visit there happened during a downturn.
The bands drawn beyond today are that same curve continued forward: arithmetic that assumes the past pattern holds, not a prediction, and if Bitcoin's growth path bends, the projected bands are simply wrong.
In words: fit one growth curve through Bitcoin's whole price history against the network's age, then draw nine bands at even steps **above** and **below** it, extended month by month to 2030.
The forward part assumes the fitted growth rate keeps holding, which nothing guarantees. The bands are even mathematical steps, not lines fitted to where the price actually spent its time.
