The Bitcoin Rainbow Chart suggests $BTC remains in historically undervalued territory heading into October 2026, with the cryptocurrency trading just above the model’s lowest valuation zone.

The Bitcoin Rainbow Chart is a long-term valuation model that uses logarithmic bands to show whether Bitcoin is trading in zones historically associated with accumulation, fair value, or market euphoria.

At press time, Bitcoin ($BTC) was trading at $86,128, only slightly above the Rainbow Chart’s “Bitcoin is dead” band, projected at $84,124.72 for October 2, 2026.

According to the BlockchainCenter Rainbow Chart, the lowest band for October 2, labeled “Bitcoin is dead,” stands at $84,124.72. The next level, “Basically a Fire Sale,” is projected at $112,145.39, followed by the “BUY!” band at $149,519.46 and the “Accumulate” zone at $203,456.75.

Further up the scale, the “Still cheap” band is positioned at $279,713.75, while the “HODL!” zone sits at $385,875.50. Above these levels, the model enters increasingly speculative territory, with the “Is this a bubble?” band at $531,713.42, “FOMO intensifies” at $712,913.64, and “Sell. Seriously, SELL!” at $970,822.48.
