Ethereum has long been at the center of attention for investors and analysts, and an interesting tool for assessing its development is the rainbow chart from BlockchainCenter. This model represents a logarithmic regression model that maps the long-term growth trend of the second-largest cryptocurrency.

Ethereum and rainbow chart

According to this model, Ethereum could reach a wide range of values by September 30, 2025. The minimum prediction suggests a level of $2,000 in the oversold zone, while the optimistic scenario points to $21,000 in the maximum bubble range. Of course, such volatility is expected with a very low probability.

Between these extremes are gradual phases reflecting market sentiment: from “undervalued” ($2,400), through “accumulation” ($2,850), to “stable” ($4,100).

Currently, according to TradingView data, the price is around $4,380, which corresponds to the “stability” zone. This indicates that if the pace is maintained, Ethereum could stay in this range or move higher—for example, to the “HODL” level at $4,900.

Factors affecting ETH growth

Ethereum is not isolated from the broader market. Its development remains closely tied to the dynamics of other digital assets and overall investor sentiment. According to analyses, Ethereum is currently in a balanced phase, but greater growth would require a stronger inflow of capital.

Another important factor is the growing interest of institutional investors. In 2025, there has been a noticeable shift of major financial players toward Ethereum, with companies like BlackRock increasing their portfolios in favor of this cryptocurrency, even faster than with Bitcoin, according to Farside data. Exchange-traded funds (ETFs) also play a crucial role, as they can bring massive investments and support long-term growth.

In conclusion, the rainbow chart is not a short-term prediction but provides investors with a framework to navigate potential development scenarios. For investors, this means a clear tool to assess whether the current price is an opportunity for accumulation or a signal for long-term holding.
