The 1-hour chart of Bitcoin forms a bearish evening star pattern, with MACD showing a death cross at a high position and RSI dropping to 42, indicating increasing short-term pullback pressure. Key support below is focused on the psychological level of 107000 and the trend support level of 106500, while resistance above is at the rebound high of 107800 and the intraday high of 108100; the 4-hour chart of Ethereum shows a long upper shadow indicating clear resistance 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 pullback risk is increasing, and attention should be paid to defending the key support levels of Bitcoin at 107000 and Ethereum at 2440. If these levels are broken, it may accelerate the decline, so it is recommended to strictly control positions and be cautious of increased volatility risks around the opening of the US market.

Bitcoin suggestion: Stabilize and go long at 106800-107000, stop loss at 106500, target at 107500.

Ethereum suggestion: Stabilize and go long at 2420-2430, stop loss at 2400, target at 2460.
