On December 15, 2025, Ethereum's technical outlook shows a weak pattern, approaching a key support level with clear resistance pressure. The following is a detailed analysis based on multi-timeframe indicators and key price levels:

1. Daily Level: As of the report, ETH is approximately $3090, with an intraday high of $3128 and a low of $3048. The daily candlestick has maintained above the middle Bollinger Band (at $3076) for three consecutive days, indicating some rebound demand. Resistance at the upper Bollinger Band is at $3317, with support at the lower band at $2835. MACD volume has decreased, with DIF and DEA oscillating below the zero line and spreading sideways. The EMA short and long-term gaps are widening, suggesting increased volatility. Short-term resistance is focused around the 3170 Fibonacci retracement level. Caution is advised as the core support zone is between $3000 and $3020, with $3000 being a critical psychological and technical threshold. Losing this level could significantly increase downside risk.

2. Four-Hour Level: The EMA trend indicator is in a contracting phase. Resistance at $3170 remains key, with support at the middle Bollinger Band at $3135 and the lower boundary at $3011. MACD volume is decreasing, and DIF and DEA are contracting at the bottom, indicating upward demand. Overall support below $3050 is relatively strong.

3. Key Price Level Transformation: The previous support zone of $3150 - $3200 has now turned into a strong resistance area. ETH needs to break through this zone with increased volume to ease downward pressure and create conditions for an upward move toward $3380. If the rebound remains weak, the previously mentioned support levels at $3000 - $3020 will face testing. Only by holding this level and mounting a strong rebound can a potential upward wave be initiated.
