Ethereum has reached a new all-time high in 2025, continuing a trend observed in previous years such as 2017 and 2021. This milestone for Ethereum often precedes broader altcoin momentum, historically leading to delayed rallies in Dogecoin. Currently, Dogecoin is trading at $0.218, marking a 5.84% decline this week. Market analysts are observing whether Dogecoin will follow its historical pattern of rallying after Ethereum's all-time high achievements. The correlation between Ethereum's breakouts and subsequent Dogecoin rallies remains a significant dynamic in the altcoin market, suggesting potential future volatility for Dogecoin if Ethereum maintains its upward trajectory.
