After Bitcoin shows signs of a short-term top, it has entered a downward correction trend, with the short-term market very weak and clear bearish divergence. This situation may lead to a decline, quickly reaching the extreme boundary of the correction, continuing downward until it breaks away from the shoulder support, which could change the overall trend; otherwise, the major upward trend remains intact. The key support zone for the correction is around 77,000 to 77,500. The short-term shoulder support is approximately 73,000, and the boundary for maintaining an upward trend in the medium to long term is 70,000. The new week's major range is most likely between 77,000 and 70,000.
