If ETH experiences a strong rise, it is often seen as a precursor to Altseason. The reason is that ETH is the mainstream coin with a market value second only to Bitcoin, and its price performance often drives market sentiment and capital flow. Once ETH steadily breaks through key resistance, investor confidence may rebound, and funds could spread from mainstream coins to other altcoins, driving the overall market up. However, whether this will come true still needs to be observed in terms of Bitcoin's trend, the macroeconomic environment, and market liquidity. A strong ETH is a necessary condition, but not a sufficient condition.
