Ethereum (ETH) is showing signs of a significant shift in its market dynamics, with technical indicators pointing toward a potential bullish breakout against Bitcoin (BTC). This pattern suggests that ETH is preparing for an upward movement, possibly leading the charge into altseason. Traders and investors are closely monitoring Ethereum’s price action, which could signal a broader market rally for altcoins.
According to Egrag Crypto on X, Ethereum’s recent price movements suggest that a multi-year reversal is underway. The expert highlights the long-term curved support line that has historically acted as a floor for ETH/BTC, with each touch of this support preceding a strong rally. The latest reaction is said to resemble previous bullish takeoffs from 2017 and 2020, signaling that ETH might be set for another explosive move.
Key Resistance Points and the Potential for a Major Breakout
A key focus in the analysis is the long-term descending resistance line that has capped Ethereum’s performance for years. This resistance, marked by a yellow curved line on the chart, has kept ETH’s price from making significant gains against BTC.

However, ETH is now pressing up against this resistance with increasing momentum, which suggests that a breakout is more likely than a breakdown. As price compression builds, the market is expected to see higher volatility, potentially leading to a macro move.
Elliott Wave Formation Signals Impending Price Surge
Moreover, the price structure follows the typical Elliott Wave formation, with the Wave 4 bottom already confirmed. This sets the stage for a final move in Wave 5, targeting key Fibonacci retracement levels. The first major target is 0.039 BTC, with higher extensions reaching 0.047–0.054 BTC, and possibly 0.073 BTC, depending on the strength of the breakout.
For Ethereum, a close above 0.039 BTC on the two-week chart would be a strong signal that altseason could be on the horizon. This move would likely trigger a flow of capital from Bitcoin to Ethereum, followed by large and mid-cap altcoins, further fueling the expansion of the altcoin market.
Ethereum’s Potential to Drive Market Growth
As the price action continues to develop, Ethereum is positioning itself for a potential breakout. If these key resistance levels are surpassed, ETH’s rally could be the catalyst for broader market growth, making it a critical moment for both Ethereum and the overall crypto market.
