Bitcoin's performance today shows a "V-shaped rebound" characteristic, rapidly pumping from the low point, but the trading volume has not increased, indicating that the long positions are not yet stable. December has historically performed strongly (the third best month), combined with ETF expansion and expectations of Trump’s policies, the long-term bullish outlook to 100,000-110,000 USD has a high probability (18-22% rise potential). However, the short-term risk is bearish: if it falls below 86K, it may test the 83K support; if it holds steady, it aims for 89K resistance.

Trading Advice:
• Long positions: Build a position near 86K, stop loss at 83.5K, target 89K.
• Short positions: If the high point meets resistance, short to 85K.
• Focus on this week's data: PCE (12/5), employment report. It is recommended to diversify risks and monitor on-chain data (such as reduced exchange inflows). 
Overall, today's rebound eased some of the panic, but the shadow of the bear market has not dissipated. Investors should be cautious and adjust their strategies based on macro signals #十二月行情展望 .
