Bitcoin showed a trend of rising first and then suppressing today, reaching a high of 102,905 points earlier, then entering a volatile phase in the afternoon, and starting to decline significantly in the evening, dropping to a low of around 99,034 points. During the same period, Ethereum reached a high of 2,296 points, then followed Bitcoin down to a dip of 2,156 points.

From a technical analysis perspective, Bitcoin has formed a three black crows pattern on the daily chart and has dipped to the important support level of 99,000. The four-hour chart shows that the MACD double lines have plunged below the zero axis, with the volume of the bars accelerating. The one-hour RSI indicator, which has a shorter time frame, shows a value dropping to 28, entering the oversold area but has not yet shown a clear divergence signal, indicating that the current rebound momentum is quite limited.

Regarding recent operational suggestions, investors should maintain a cautious attitude and consider setting short positions at high levels. Bitcoin can focus on short opportunities in the 100000-100500 range, targeting the 98500 level; Ethereum can consider short positions near 2220, targeting the 2120 level.

In a weak market environment, it is advised that investors avoid counter-trend operations. Only when there are clear reversal signals and the price successfully holds above the support level should adjustments to the operational strategy be considered. In the current downward trend environment, risk control should take precedence, and ensuring the safety of funds is the most important.
