$ETH investing in ETH should remain rational. First, conduct in-depth research on the development of the Ethereum ecosystem, technological upgrades, and other fundamentals to assess long-term value. Closely monitor market dynamics and use technical analysis to seize entry opportunities. Strictly control positions, set stop-loss and take-profit levels, and avoid blindly chasing price increases or selling off during declines. At the same time, diversify investments to reduce the risk of a single asset and maintain a calm mindset to cope with price fluctuations.
