Thursday morning BTC technical analysis.

From the 1-hour chart, the bearish pattern still dominates—EMA5 has crossed below EMA10 and EMA20, and the MACD death cross is also in the consolidation phase. However, there is a detail worth noting: oversold signals have already appeared, and the lower Bollinger Band at 90458 coincides with last night's low of 90614, forming a resonant support.

Switching to the 4-hour chart, some different signals can be observed. RSI remains in the oversold zone but shows signs of a rebound, KDJ has already formed a golden cross at the low and is beginning to rise, indicating a potential short-term rebound. Multiple moving averages below 90000 provide support, and the lower Bollinger Band has not yet expanded, so it is likely to oscillate within the 90000 to 95000 range.

**Trading ideas**:
- Main bearish approach: Light short positions above 92500, targeting the 91700-90800 range. If it breaks below 90500, there is a chance to hold for a move towards 90000.
- Supplementary bullish approach: Buy on dips below 90800, targeting 91500-92500. If it breaks through 92500, it could aim for the previous high near 93000-93500.
- The key is to keep a close eye on the 90000 level; if support holds, the rebound potential will be greater.
