BTC's daily chart has been in a long-term sideways range, with no significant bullish or bearish trends. Short-term, small-scale spikes and drops are just noise and lack trend reference value. Key observation signal: Bitcoin breaking upward out of the descending channel is the critical confirmation signal for a trend to start. Only after the breakout will the bullish trend unfold. 64,500-65,400 is the key dividing line: once broken, it will shift from resistance to support, and the price will continue upward. Breaking the 67,000 neckline resistance is necessary for a unilateral bullish trend to emerge.
