BNB, after a significant drop yesterday, saw an early rebound today and is currently facing resistance at 850. The 4-hour chart maintains an upward channel, and the continuous bearish candles have not led to substantial changes in the overall trend. The short-term downside space is limited, and it is recommended to buy on a pullback this afternoon. Consider buying in the 846-842 area, aiming for 858-870, and if it breaks through, continue to look for 880.
