Tonight at 22:00 (Beijing time), Federal Reserve Chairman Powell will deliver an important speech at the Jackson Hole annual meeting. This speech is seen as key to influencing the direction of monetary policy in September, and global financial markets are closely watching. For cryptocurrency investors, this is a time that requires heightened vigilance.

This speech may involve three important aspects:

1. Interest Rate Policy: If Powell hints at slowing the pace of interest rate hikes, it may stimulate an increase in Bitcoin prices.
2. Inflation Attitude: If it indicates that inflation is being controlled, market sentiment may quickly improve.
3. Economic outlook: Mentioning recession risks may prompt some funds to flow into encryption as a safe haven.

Historical data shows that Powell's speeches often trigger market volatility. After his speech in August last year, Bitcoin rose 10% in a single day. After mentioning interest rate hikes in June this year, the market experienced a process of declining and then rising. This indicates that each speech may contain investment opportunities, and the key lies in whether investors can seize them.

Considering the potential for significant volatility, different types of investors can adopt different strategies:

- Short-term traders may consider reducing their positions before the speech and wait for a clear direction before taking action.
- Leverage traders must set stop-loss orders to prevent liquidation risks caused by severe fluctuations.
- Spot investors may view significant declines as potential buying opportunities.

In addition, the trends in related markets are also worth paying attention to:

- The fluctuations of the US stock market, especially the Nasdaq index futures, may affect the encryption currency market.
- The significant increase in gold prices may drive the price of Bitcoin.
- If the dollar index falls below a key level, it may drive the encryption prices of cryptocurrencies up.

Regardless of market fluctuations, investors should remain rational and avoid blindly chasing prices or over-investing. It is wise to execute a pre-established trading plan and control risks. This evening could become a turning point in the encryption market, making it worthy of close attention from all investors.
