Bitcoin Rainbow Chart Screensaver

The Bitcoin Rainbow Chart screensaver plots Bitcoin's real live price against the well-known logarithmic rainbow chart valuation bands, computed from the model's own published formula. It's a popular but unofficial model, clearly labeled as such. It's free, runs in your browser, and ESC exits.

How the Bitcoin Rainbow Chart screensaver works

The rainbow bands are computed from the model's real published logarithmic-regression formula, based on Bitcoin's real genesis date.

The saver fetches Bitcoin's real live price from CoinGecko, with no key required.

A marker plots exactly where today's real price sits within the band structure.

The price marker updates live as the real market moves.

A worked example

If the real price sits in a lower band, the chart reads as "undervalued" by this particular model's own colour scheme — a popular framework among some traders, not a guarantee of anything.
