Bitcoin Rainbow Chart predicts BTC price for start of September

The Bitcoin Rainbow Chart indicates that Bitcoin (BTC) could trade around $63,800 at the start of September 2026, based on the model’s current trajectory.

With Bitcoin changing hands at $63,258 at press time, the forecast implies a modest gain of less than 1% over the next two weeks.

The Rainbow Chart is a long-term valuation model that maps Bitcoin’s historical price action against a logarithmic growth curve to indicate whether BTC appears overvalued or undervalued relative to past market cycles.

Based on the chart’s current trajectory, Bitcoin is trading near the lower end of its historical valuation range, with the model implying a price of roughly $63,800 by early September. However, the Rainbow Chart is best viewed as a long-term valuation tool rather than a precise forecasting model.

The latest data also shows the cryptocurrency trading below the original chart’s lowest band, a zone BlockchainCenter labels “Bitcoin is dead.” Historically, similar periods have reflected extreme market pessimism and have often preceded long-term recoveries.

Notably, the Rainbow Chart divides Bitcoin’s valuation into color-coded bands representing different market conditions.
