Bitcoin has recently fluctuated frequently, indicating that a significant resistance has formed around the 108,000 level. Today's market trend is similar to yesterday's, with multiple attempts to break through the upper resistance level but failing to succeed, ultimately retreating and forming an upper shadow. This repeated attempt to break through but inability to stabilize suggests that the daily level has shown signs of pressure and retreat.

In the short term, Bitcoin seems to have entered a slow oscillating downward trend. The current price is oscillating between the middle and lower bands of the Bollinger Bands. Given the current market environment, investors may consider following the trend and making moderate moves at the rebound highs.

For specific strategies, investors can focus on shorting opportunities around the 107500-108000 range, with a target set at 105500. Regarding Ethereum, opportunities to short can be found around 2500, with a target price of about 2350.

It is important to note that the cryptocurrency market is highly volatile, and investors should operate with caution and manage risks effectively. At the same time, market conditions change rapidly, so it is advisable to stay updated on the latest developments and adjust strategies accordingly.
