$ETH Investment in ETH should remain rational. First, deeply research the fundamental aspects such as the development of the Ethereum ecosystem and technological upgrades to assess long-term value. Closely monitor market dynamics and use technical analysis to grasp the timing of entry. Strictly control positions, set stop-loss and take-profit levels, and avoid blindly chasing highs or selling at lows. At the same time, diversify investments to reduce the risk of a single asset, and approach price fluctuations with a calm mindset.
