Bitcoin is currently consolidating around 75,500, and the daily chart remains within an upward channel. Overbought pressure has been digested, and indicators are gradually turning stronger. The key support for the bulls is at 73,600-73,000, while resistance above 76,500-77,500 is relatively heavy, making short-term rapid breakouts difficult. The 4-hour chart has rebounded from lower levels, but upward momentum is limited; when it encounters heavy pressure, it turns back. The 1-hour chart shows a contracting-volume range-bound movement, with no one-way bias. Today’s trading range is between 74,000 and 77,000 for selling high and buying low.
