Yesterday the market was range-bound with Bitcoin fluctuating in a narrow range. By night, the bears plummeted, dropping again to 590. While the bears celebrated, the longs became fuel. Currently, the technical structure has weakened overall, with a short-term double bottom at 590, followed by a slight resistance at 612 on the rebound. On the four-hour chart, after consecutive bearish candles with solid volume, small bullish candles appear, indicating limited rebound momentum. For this morning, it's suitable to short following the trend. Short near 610-616, target 600-590. Focus on 590; if broken, the bears will continue to decline with volume; if not, reverse for a short-term long.
