Last night's market dipped as expected, with the effect of whale long positions compounded by pressure from the US stock market opening, causing Ethereum to test the 4050-4080 range. We entered the market accordingly and have already doubled our position. In the short term, if the rebound target can be seen at 4215, if it goes down, we need to be cautious of support at 3971 and 3915. Next, we will focus on capital flow, market sentiment, and major events to avoid blindly chasing orders. A reminder to everyone: always set stop losses when opening positions, profit relies on trends, and safety relies on discipline. $ETH
