The 1-hour chart for Bitcoin has formed a evening star bearish pattern, with MACD showing a death cross at a high level and RSI retreating to 42, indicating increased short-term pullback pressure. Key support below is at the psychological level of 107000 and the trend support level of 106500, while resistance above is seen at the rebound high of 107800 and the intraday high of 108100; the 4-hour chart for Ethereum shows a long upper shadow indicating significant pressure above, with short-term resistance in the range of 2480-2500, and support at the intraday low of 2440 and the trend line at 2420. The current market faces increased pullback risk, requiring close attention to the defensive situation at the key support levels of 107000 for Bitcoin and 2440 for Ethereum. If these levels are breached, it may accelerate the downward movement, and strict position control is advised. Caution is warranted around the opening of the US market for heightened volatility risk.
