On the four-hour level, the price received support at the middle band of the Bollinger Bands and closed several Bullish lines, but it is still trapped between the middle band and the upper band, failing to effectively break through and reclaim the previous key resistance area. The selling pressure at high levels is significant, and the buying momentum is relatively insufficient. From the one-hour level, the middle band of the Bollinger Bands continues to move downward, gradually increasing pressure, and market momentum is weakening, with the overall structure leaning towards short positions.

Therefore, the trading strategy recommends focusing on short positions on rebounds.
The specific operation can continue the strategy from the early morning:
For Bitcoin, short positions can be gradually established in the range of 88,500 to 89,000, targeting around 85,000.
Consider entering short positions around 2970 for Ethereum, targeting around 2,800.
