On December 14, 2025, BTC is in a critical fluctuation period with unclear market direction. There is a lack of liquidity on weekends, and the focus is on tonight's early hours. Today's analysis: During the Asian trading session today, BTC returned to the $90,000 mark, fluctuating in the range of $89,000 - $91,000. Due to poor market liquidity over the weekend, volatility is relatively calm, but there are concerns that there may be market fluctuations on Sunday. The upper side faces strong resistance between $94,150 - $94,236, while $90,000 serves as a key psychological support level. If it breaks below this, it may drop to the $85,900 - $86,300 area, and there is also strong support at the $88,000 level. The daily MACD shows bullish signals, but the RSI has not broken through the 50 midline, indicating insufficient upward momentum. The 4-hour chart has formed a 'double top' pattern and is still at the end of a triangular consolidation, under pressure from multiple moving averages, with short positions dominating in the short term. Meanwhile, the key point is around the $90,700 mark on the 4-hour Bollinger Bands midline. Currently, BTC is at a key technical pivot point for the year-end trend, and we need to wait for a breakout above the resistance area near $94,200 or a drop below the $90,000 support for a clear direction #加密市场观察 #BTC走势分析 $BTC
