Bitcoin continues its strong bullish trend, quickly surging from around 79,700 in the early session, touching 81,200 at midday before a slight pullback and consolidation, in the evening it moves in tandem with the US stocks reaching new highs, with a peak testing 81,700. In the early morning, it remains in a high-level narrow range, pulling back to around 80,800 and entering a tug-of-war state. Technically, the daily chart shows a clear bullish arrangement, with the 5/10 moving averages diverging upward, and the 80,000 level has shifted from previous resistance to strong support; the hourly chart displays a “surge - pullback - re-acceleration” stepwise upward structure, with 80,800-81,200 as the short-term dividing line between bulls and bears, and repeated tug-of-war in this range highlighting increasing market disagreement. On the trend level, the major trend (daily/weekly) remains oscillating upward, with a complete mid-term upward cycle, and key resistance concentrated around 81,500-82,000 (near the 200-day moving average); the smaller trend (15-minute/1-hour) is in high-level oscillation leaning bullish, with short-term moving averages converging and then diverging again, declining volume indicates strong wait-and-see sentiment among bulls and bears, and there is a lack of clear short-term directional guidance. Overall, the bullish trend remains intact, but profit-taking at high levels has weakened upward momentum, likely leading to continued consolidation in the 80,800-81,700 range in the short term. Attention should be paid to the effectiveness of the 80,800 support and the strength of the 81,700 breakout; a volume-driven breakout could open upward space, while a break below support risks a phase correction.
