Bitcoin yesterday morning tested a bottom at 73,680 USD before starting a stepwise rebound, surged in the afternoon to 75,500 with a slight pullback, and after gaining strong support at 74,500, it moved up again, rising to 76,500 in the early hours but encountered resistance, currently consolidating around 75,600, maintaining an overall bias towards a corrective upward structure; in the short term, focus on the resistance at 76,500, an effective breakthrough could lead to further gains, while a break below 74,500 or even 73,200 would signal a breakdown of this upward trend channel.
