Bitcoin's price has fallen below $90,000 in the fourth quarter of 2025, breaking a significant support level and sparking discussions of a potential bear market. The cryptocurrency breached the 50-week exponential moving average (EMA) in mid-November, a critical marker for support and resistance, leading to increased bearish sentiment. On-chain data indicates that Bitcoin could potentially drop to the $60,000-$70,000 range, aligning with historical bear market trends. However, a recovery above $98,000 or a reclaiming of the 50-week EMA would suggest renewed bullish momentum.
