Bitcoin has experienced a deep correction and is currently in a low-range oscillation and recovery phase. The Bollinger Band midline (around 69,574) is hovering nearby, while the upper band (around 71,783) forms a short-term strong resistance level. The Bollinger Bands are beginning to narrow, indicating that volatility is decreasing and the market is accumulating energy, waiting for a trend reversal. The KDJ has formed a golden cross signal, with values near the 50 midline, showing signs of strengthening short-term momentum and a continued rebound and recovery need. Although the MACD green histogram has shortened, indicating weakening downward momentum, the bearish alignment pattern remains unchanged, and the strength of the rebound still requires observation.
