From the 4-hour chart of BNB, the Candlestick Chart shows a clear rise trend, which strongly indicates that there is upward momentum in the current market. If there are no obvious fall signals in the upcoming trades, we have reason to believe that the market price is likely to continue to climb.

For short-term traders, the area around $850 may become an important support level. If the price retraces to this level, it may provide a good entry opportunity for investors. For those who have already established long positions, $870 can be seen as a potential target price.

However, investors should remain vigilant and closely monitor market trends. Although the current trend is positive, the cryptocurrency market is highly volatile, and any unexpected event could lead to a rapid change in market sentiment. Therefore, before making any trading decisions, it is advisable for investors to consider multiple factors comprehensively, including but not limited to technical analysis, fundamental analysis, and overall market sentiment.

Remember, a reasonable risk management strategy is crucial for achieving long-term success in this highly volatile market. No matter what trading strategy you choose, you should set clear stop-loss levels to prevent excessive losses from potential significant falls.
