The 8-Year Ethereum Convergence Indicates a Coming Altcoin Season Stronger Than 2021

A recent analysis highlights a significant eight-year convergence pattern in the Ethereum (ETH)-Bitcoin (BTC) trading pair, suggesting the impending arrival of a robust altcoin season. Although rumors of an altcoin season have persisted since before 2025, they have not yet become a reality, illustrating the ongoing volatility among alternative cryptocurrencies. The analyst believes the new convergence structure could lead to an altcoin season that surpasses the one seen in 2021.

Ethereum Chart Structure Points to a Major Altcoin Season

Crypto analyst CW has unveiled a promising technical analysis forecasting a significant altcoin season in the current market cycle. This analysis focuses on the ETH/BTC trading pair and reveals an intriguing convergence pattern that has been taking shape since mid-2017.

In CW's post on X, he predicts that this convergence could break during the ongoing bull market. The structure is apparent on the weekly chart as a sizable descending triangle, originating when ETH/BTC reached a high of around 0.16. Since then, the pair has been compressing between a downward resistance line and a steady support level near 0.020.

The chart illustrates that ETH/BTC peaked during the bull market of 2021 but did not break through the upper descending trendline of the convergence pattern. After that failure, the pair fell sharply and has continued to decline, now nearing the tip of the convergence pattern close to 0.029.

This behavior indicates that ETH/BTC is nearing its final stage at the peak of the descending triangle. The diminishing gap between resistance and support suggests the market may be reaching a pivotal moment. CW believes a breakout from this point could conclude the trading pair's eight-year compression within the convergence, potentially shifting strength from BTC to ETH, and then to the broader altcoin market as we move toward an altcoin season in 2026.

Anticipating a 2026 Altcoin Season Stronger than the 2021 Boom

CW further emphasized that the upcoming altcoin season he foresees could surpass the strength of the 2021 cycle, reminiscent of the explosive growth observed in 2017. He points out that many investors underestimate the power of the 2017 bull run, which resulted in broader and more aggressive gains across the altcoin sector compared to the more selective rally of 2021.

In a previous analysis, CW presented another chart from CryptoQuant, bolstering his prediction for a 2026 altcoin season. This chart monitors the centralized exchange (CEX) volume ratio of non-BTC assets versus Bitcoin, excluding stablecoins, drawing comparisons between the current market conditions and the altcoin season in 2021.

During both phases, altcoin trading on centralized exchanges consistently outperformed Bitcoin's trading volume. However, CW notes that this activity has persisted for a longer time in 2026 than in 2021. He believes that this prolonged volume, alongside a potential breakout from the current ETH/BTC convergence, strengthens the likelihood of a powerful altcoin season in 2026.
