Ethereum daily chart has broken above the 5-day moving average and surpassed the resistance of the 90-day moving average. However, from the 4-hour perspective, it is still within the 4-hour rebound cycle starting from 2775, having already completed three upward waves. Therefore, caution is advised regarding resistance at the upper boundary of the daily central zone around 3400-3447. Intraday resistance is expected in the 3400-3450 range, with support around 3280-3250. Trading ideas:

1. If it pulls back, consider buying on dips in the 3300-3280 area with a stop loss at 3250 and take profit at 3380-3400.
2. If it rises to the 3400-3450 zone, consider shorting in parts, with a stop loss at 3470 and take profit at 3320-3280.
