BNB coin has shown a certain degree of Rebound momentum on the 4-hour chart, but it is worth noting that the price has not yet effectively broken through the key technical resistance level of 650 dollars.

Technical analysis shows that from the 4-hour time frame, the MACD histogram remains in the negative zone, while both the fast line and slow line are below the zero axis, indicating that bearish strength still dominates the market. More importantly, the daily MACD indicator has formed a death cross pattern, further confirming the technical signal that the market may continue to be under pressure in the near future.

Based on the current technical formation, market participants may consider positioning short strategies in the $644-650 range, with a downside target price pointing to around $620. Investors should closely monitor the potential impact of international geopolitical factors and Federal Reserve policy trends on the cryptocurrency market, and manage risks appropriately.
