Tonight, the Fed Chairman will deliver an important speech, and the market is generally following the potential differences between him and the Treasury Secretary. Currently, major crypto assets like Bitcoin and Ethereum have not formed a clear trend, and significant fluctuations are expected during the speech. It is advisable for investors holding crypto positions to take appropriate risk management measures and set stop losses to avoid potential large falls. Although the Jackson Hole meeting is highly anticipated, investors should also pay attention to Asian family offices' allocation attitudes towards crypto assets, which may have additional impacts on the market. In this period of uncertainty, cautious operations and strict risk control are particularly important.
