From the four-hour chart, although BNB has rebounded to around 657, there is moving average resistance in the 660-665 area. The MACD has turned positive but the momentum is not strong, and the KDJ's J value has already reached 98, indicating overbought conditions.

Chasing long positions at this level carries high risk; it might be worth trying a small short position with a stop loss placed above 665. If it breaks and stays above 665, then consider stopping loss and observing.
