Bitcoin is currently at a critical support level. The daily chart shows that after finding support around 89,200, the price stopped falling. The key now is whether this level can hold. From the 1-hour timeframe, although the price briefly dipped below 89,200, it quickly recovered. The short-term trend is expected to fluctuate around 90,000, with resistance mainly focused on the 92,000 level on the 4-hour chart.

Ethereum's situation is similar. The daily chart remains bearish, with the price retracing to around 3,050. This price range (3,030-3,050) has now become a critical support zone. Holding this level suggests the downtrend may be contained. In the short term, support is at 3,090 on the 1-hour chart, and 3,040 on the 4-hour chart, with resistance facing 3,150.

Based on the above technical analysis, the midday trading strategy is as follows:

**Bitcoin**: Consider going long around 90,000, with 89,200 as an ideal entry point for adding positions. Set target levels at 91,500 and 92,000. If the price breaks through the 92,500-93,500 zone, prepare for a short position, expecting a pullback of about 2,000 points.

**Ethereum**: Position long trades around 3,085, adding more if the price retraces to 3,030. The targets are also in two stages: first at 3,150, then at 3,180. If the price reaches 3,180-3,230, consider short positions, expecting a pullback of about 100 points.
