The medium-term structure of BNB has been broken, and currently on the 4-hour chart, it is approaching the 800-820 demand zone. Previously, the resistance at 880-900 was rejected, indicating a clear bearish control intention, but the price is now touching a historically strong support zone. From the trading volume perspective, selling momentum is waning, and buying interest is beginning to gather. This area is often a key point for a rebound—whether it can hold here directly affects whether the structure can be reclaimed later.
