From a technical analysis perspective, Bitcoin's current trend faces a critical juncture. The upper level of 95,000 poses significant resistance, while the lower level of 91,600 serves as an important short-term support line. If this support is breached, the price may drop again to around 90,600. On the daily chart, following the close of a doji pattern, the price has maintained a high-level consolidation, with bullish momentum showing signs of weakening, although no clear top reversal signal has emerged. Investors should be highly vigilant; if the 91,600 support is lost, the likelihood of bearish patterns such as 'double top' or 'head and shoulders' forming will significantly increase.

On the 4-hour chart, Bitcoin's price continues to be constrained by the MA10 moving average (dynamic resistance), while the MACD indicator has formed a death cross at a high level, and the volume of energy bars is continuously decreasing. These signals all suggest that the probability of a price pullback in the short term is quite high. Based on this, it is recommended that investors consider attempting short positions in the range of 94,000 - 93,500, targeting price levels at 91,600 - 90,600.

As for Ethereum, the daily chart exhibits a downward structural characteristic, with the price rebounding to the 1,800 level encountering obvious resistance, while the lower level of 1,720 becomes a critical support level. In the short term, Ethereum is likely to maintain a range-bound operation between 1,720 and 1,800. Analyzing the 4-hour chart, the price is at the upper range, and the RSI (14) indicator is close to the overbought area. If it cannot effectively break through the 1,800 resistance, a pullback to test the lower support is expected. Therefore, when the price is under pressure in the range of 1,790 - 1,800, it is advisable to lay out short positions with a target at 1,750 - 1,720.
