According to past trends, Ethereum's highest point is 4.8K, and the lowest point after a pullback is 3.3K. This time it only rose to 4.2K, so a pullback to 3.1K is not surprising. If it goes below 3.2K, I will buy directly and take profit at 3.6K. I don't have money this time and don't dare to buy, and my position was opened at 4.0K, so it's basically very difficult to go back.
