After the Christmas holiday, Bitcoin rebounded to around 88,590 but quickly dropped back to around 86,500. The market shows a typical weak rebound pattern, falling upon encountering resistance. This range has been tested multiple times: the current strategy should focus on selling at high levels, with buying on dips as a supplement. The short-term rebound is insufficient to change the overall bearish trend.

From the candlestick structure, the selling pressure above remains heavy. Each rebound lacks effective buying support, and prices often drop immediately near key resistance levels. This fully indicates that market bullish sentiment is not strong enough. As long as the 90,500 level cannot be effectively stabilized and broken through, the short-term weakness is unlikely to reverse. These short-term rebounds are better seen as technical corrections within a downtrend rather than trend reversal signals.

In terms of trading strategy, focus on shorting around 89,000-89,800, with the first target near 87,000-86,500. Maintain respect for resistance levels in the short term, avoid chasing high, and wait for clearer breakout signals before adjusting your strategy.
