December 16, 2025 $BTC is in a clear 4-hour downtrend. All major technical indicators (EMA bearish alignment, MACD weakening below zero, RSI entering oversold territory) support this assessment. Although short-term indicators show oversold conditions that may trigger a technical rebound, the trend remains bearish until the price effectively breaks above key resistance levels (such as 89,500).

Operational advice: Trend traders should mainly consider shorting on rallies or staying on the sidelines. If aiming for a rebound, closely monitor resistance levels above and set strict stop-loss orders. If the price drops below 85,000 with high volume, the downtrend could intensify. Risk warning: Cryptocurrency markets are highly volatile. The above analysis is based on historical data and does not constitute investment advice. Please make decisions based on real-time market conditions and your own risk tolerance.

Key Level Analysis
Upper Resistance Levels (Key Pressure Levels):
1. 89,000–89,500 area: This is the recent consolidation zone's lower boundary before the breakdown and is near the EMA slow line (89,132), which will serve as the first strong resistance during a rebound.
2. 90,000–90,500 area: The convergence zone of EMA fast line and previous K-line highs, a psychological barrier.
3. 92,000–93,000 area: The rebound high zone formed on December 11-12, representing a stronger resistance zone.
Lower Support Levels (Key Observation Levels):
1. Current low of 86,345: The latest support level; a break below this could open further downside.
2. 85,000–85,500 area: Near the recent low of 85,146 on December 15, this is a strong support zone.
3. 84,000 psychological level: If 85,000 is lost, the next important psychological and technical support level.
