Recently, the Federal Reserve's policy expectations have shifted, causing market sentiment fluctuations, and the cryptocurrency market has also experienced oscillations and a downward trend. The short position strategy deployed yesterday has yielded considerable profits, with Bitcoin reaching triple-digit gains, and Ethereum easily breaking through a hundred points.

From a technical perspective, Bitcoin and Ethereum surged yesterday but then pulled back, forming long upper wicks on the daily candlestick chart, indicating significant selling pressure above. Coupled with the rising end-of-year cash-out sentiment, the short-term market is likely to remain in a high-level oscillation pattern, with little chance of a sharp rise. Instead, there are still opportunities to short at the rebound highs.

**December 30th Short Position Strategy Reference:**

For Bitcoin, continue shorting on rebounds to the 89,000-89,500 range; conservative traders can wait for 90,000-90,500 before entering. Set the stop-loss around 91,500. Downside targets are sequentially 88,000-87,500-87,000. If the price continues to break down, focus on the 86,500-86,000 range, and adjust stop-losses flexibly based on the trend.

For Ethereum, continue shorting on rebounds from 3000-3030; conservative traders can enter at 3060-3090. Set the stop-loss near 3130. Target levels are 2950-2900; if broken, watch for 2870-2850, and move stop-losses to protect profits if the downward momentum continues.

**Bullish Alternative Strategies:**

Aggressive traders may consider going long when Bitcoin retraces to 86,000-86,500, with a stop-loss at 85,000. Targets are 87,500-88,000-88,500-89,000 step by step; if broken, then look for 89,500-90,000.

For Ethereum, go long on dips to 2860-2900, with a stop-loss at 2820. Targets are 2950-2980-3000-3050.

In the current high-level oscillation pattern, there are actually many opportunities for selling high and buying low, allowing traders to capture swing gains every day. Wait for the pattern to truly break before following the trend. In the short term, there are no strong positive or negative catalysts, so avoid blindly chasing shorts or longs. Maintain rhythm and control risk—that's the correct approach in a volatile market.
