Bitcoin Rainbow Chart
Loading the Rainbow chart…
The Rainbow chart overlays Bitcoin's price (log scale) on a logarithmic regression of its whole history. Each colored band is a fixed step (×1.3) around that trend line: cooler blues near the bottom mark historically cheap zones (“Fire Sale”, “BUY!”), warmer reds near the top mark historically expensive, euphoric zones (“FOMO”, “Maximum Bubble”). Dashed lines mark Bitcoin halvings (2028 and 2032 are estimates). It's a long-run statistical model for context only — not a prediction or financial advice. Hover for the price and every band value on any date.
