ETH is currently experiencing significant volatility, with the price sharply retreating from the upper Bollinger Band and moving towards the middle band downward. In terms of technical indicators, the MACD red bars are decreasing, and the Trading Volume remains low.

The market's focus is concentrated on the key price level of 3500. If it falls below this level, the next support level may be around 3430; if it can hold, it may rebound to test the resistance level of 3550.

It is worth noting that while non-farm data may bring short-term volatility, in the long run, expectations for interest rate cuts may still become a positive factor. In addition, the ETH2.0 upgrade process and ETF expectations are also key points of market attention.

For investors, the current market volatility may present opportunities. Consider opening a short position near 3520 while setting a long limit order at 3430. If it breaks through 3550, consider adding to the long position.

However, each investor should make decisions based on their own risk tolerance and investment goals. Whether it's buying high and selling low, waiting for a pullback to buy, or taking the opposite approach, careful assessment of market conditions is required.

Finally, let me reiterate one point: if you are repeatedly frustrated in the cryptocurrency market, perhaps you should reassess your investment strategies and methods. Success often comes from the right approach and continuous learning.
