The market is like the tide, rising and falling in an orderly manner. Wise traders act as helmsmen steering the ship, while most retail investors often find themselves passive when the wave turns.

The current four-hour chart still shows room for decline, with Bitcoin continuously testing lower support levels. Although bulls are attempting to break the trend, overall momentum is clearly weak. The rebound from the previous strong dip was essentially a correction, serving as a buffer for the subsequent continuous decline. Currently, the Bollinger Bands are expanding, with the middle and lower bands continuing to decline, and the short-term trend shows two bearish candles engulfing a bullish candle—indicating a high probability of the downtrend continuing.

Switching to the one-hour chart, Bitcoin has seen a series of bullish candles rebounding, but it has sharply pulled back before reaching the resistance level above, further confirming short-term momentum is insufficient. The lows below continue to be refreshed, and the entire downward channel has fully opened. Before a strong stretch occurs, the trading strategy should focus on shorting rebounds.

**Specific advice**: Bitcoin can be shorted around 87200-87700, targeting near 86000; Ethereum can be shorted around 2930-2950, with attention to support zones at 2800-2850.
