Ethereum overnight dipped to around 2870, then stopped falling and rebounded. The intraday level continues to operate within the daily center around 2775-3447. The current decline starting from 3403 has already formed two 30-minute centers. Today, focus on Ethereum's oscillation and breakout around the 30-minute center 2. Watch for resistance in the 3060-3090 area of the 5-day moving average above, and support in the 2930-2900 area below.

The operational approach remains oscillatory: 1. Short near the 3070-3090 area with a stop loss at 3120, take profit at 2970-2950. 2. Long near the 2950-2930 area with a stop loss at 2900, take profit at 3050-3070.
