The Ethereum market has recently shown an interesting pattern, particularly with frequent rebounds around 6 AM. For the upcoming market trend, we need to closely follow the key price level of $4440. If it can hold above this level and not fall below it within an hour, we may see a pump to repair the market. Conversely, the market may continue to oscillate downwards.

It is worth noting that if a Rebound occurs at 6 AM, its strength may not be particularly strong. Investors can use the $4550-4560 range as a reference, after which there may be shorting opportunities.

For short-term trading strategies, consider setting a long position near $4350, while setting a stop-loss point below $4300. The upper target can be aimed at the $4500-4560 range.

In addition, the trend of the 'Silk Road' cryptocurrency is also worth following. After experiencing a rebound recovery, a second significant fall may occur.

Recently, the U.S. Producer Price Index (PPI) year-on-year for July was higher than expected, which may have some impact on the cryptocurrency market. At the same time, we have also seen a phenomenon of rotating pump in mainstream coins, indicating that the market's activity is on the rise.

Overall, the current cryptocurrency market is in a critical period, and investors need to remain vigilant, closely follow various indicators and news updates in order to make informed investment decisions.
