Bitcoin continues to attract investors’ attention as its price dropped to the 110,000-dollar mark, according to data from TradingView. According to an analysis published on Finbold, the price could range widely from $36,628 to $409,725 by September 30, 2025. This estimate is based on the so-called Bitcoin Rainbow Chart, which uses logarithmic regression to display historical trends and market sentiment through colored bands.

Bitcoin and the significance of the chart bands

Currently, Bitcoin is at the lower boundary of the “HODL” zone, which ranges from $108,470 to $142,332. In practice, this means long-term investors should not rush to sell or buy but maintain their positions. History shows that this band represents a fair value where risk and potential are balanced.

The Rainbow Chart from Blockchain Center offers multiple zones reflecting moods from pessimism to extreme optimism. At the bottom of the spectrum is the sell-off band, signaling significant undervaluation between $36,628 and $47,947. This is followed by the green accumulation zone, encouraging investors to make gradual long-term purchases.

It should be emphasized that the Rainbow Chart is not a traditional predictive model. Instead of providing exact forecasts, it provides a framework for understanding market cycles and allows investors to see the current sentiment phase of Bitcoin. This makes it a useful tool for strategic decision-making in the volatile crypto market.

What to expect from September?

According to the color spectrum of its historical cycles, Bitcoin indicates that each peak forms lower than the previous one. Theoretically, Bitcoin could reach a peak in the orange zone, i.e., between $181,644 and $233,215. A more conservative estimate places the possible peak in the band from $142,332 to $181,644.

However, growth to these levels would likely occur in the last quarter of the year, as data from Coinglass shows this period is historically the most profitable for Bitcoin. On the other hand, September is the least profitable month of the year, so significant upward volatility is not expected.

In other words, during September, it would be considered a success if Bitcoin surpassed its all-time high of $124,500. Otherwise, it may also experience a decline, reflecting the seasonal and cyclical behavior of the market. Investors should therefore be prepared for a relatively calm, possibly slightly declining period.
