ETH prices always swing between two extremes. When market enthusiasm is high and FOMO is rampant, it's often a good time to short; conversely, when sentiment is low and panic spreads, there are opportunities to accumulate at lower levels. This pattern has been proven time and again—those who chase the highs and sell the lows are always the last to pay the price, while those who calmly observe market sentiment cycles tend to come out ahead in the end. Mastering this rhythm can significantly improve trading efficiency.
