📢 Strategy Explanation:
Currently, ETH shows a slight rebound, but lacks volume and momentum; many technical indicators remain bearish. Structurally, 2550 has become a strong upper resistance, and the short position is ideal. If it retraces to the 2450 or even 2430 area, it will form a potential double bottom, at which point we can observe whether it turns bullish. The current strategy should focus on 'inducing buying before a drop' as the main expectation, following the trend and strictly controlling risk.
