From the daily chart perspective, Bitcoin has been closing lower for several consecutive days. Currently, the price has broken below the previous key consolidation zone, testing the support strength in the 66,000-66,500 region. The candlesticks are far from the short-term moving averages, with a large divergence, indicating a need for technical correction. However, the MACD has formed a death cross and is diverging downward, with the green histogram bars continuing to expand, suggesting that the daily adjustment is still ongoing. Over the weekend, trading volume has decreased, and the market is likely to remain in a low-range consolidation. On the four-hour chart, after breaking below the key resistance at the 120-day moving average, the price continued to decline. The Bollinger Bands are gradually narrowing and trending downward, indicating a strong bearish tone. In the short term, a breakdown below the 66,000-66,500 range should be monitored, and as the range shifts lower, attention should be paid to the resistance at 67,500. For now, on Sunday, maintain a sideways outlook and wait for Monday to confirm the direction.
