Bitcoin remains within the downward correction trend boundary at 71,500. Currently, the market shows a tendency to break to new lows. If the rebound within the range cannot break above 71,500, the downward trend will continue, with the correction target adjusted to 65,900. This rebound to the resistance level is very critical and will determine whether next week closes higher or lower. If the rebound breaks above 71,500, it is possible to directly reach 74,200, and then return to around 70,000 to resume the upward trend. Next week is expected to close higher. The key point to watch is the critical level at 71,500.
