The cryptocurrency market has experienced significant fluctuations today, with investors' focus concentrated on the upcoming speech by Fed Chairman Powell. The market is divided on whether interest rate cuts will begin in September, which has led to the current whipsaw market, causing some investors to be shaken out.

Analysts predict that Powell's speech may present three scenarios:

1. Clearly signaling a rate cut in September, this will bring positive news, and the market is expected to welcome a rebound, with a probability of about 20%.
2. Indicates that it is currently not suitable to cut interest rates, but suggests the possibility of a rate cut in the future, which is also seen as a positive signal, with a probability of about 50%.
3. Completely not releasing expectations of interest rate cuts, and even strengthening hawkish positions, may trigger a new round of declines, with a probability of about 30%.

In the face of the current situation, rational investors recommend adopting a staggered buying strategy and patiently waiting for a market turnaround. Notable tokens to pay attention to include BIO, SKL, PHA, ZEC, and JUV.

In addition, the recent all-time high of BNB and the surge of MEME tokens have also attracted market attention. Investors should closely watch the Fed's July meeting minutes for more clues on policy direction.

In this uncertain market environment, it is crucial to remain calm and rational. Investors should develop appropriate investment strategies based on their own risk tolerance and constantly pay attention to market dynamics and policy changes.
