Trump release "cooling" signal on Greenland issue, market risk appetite rises, gold pulls back, crypto market rebounds. Bitcoin daily level continues to operate within the 84500-94500 range near the daily center. The decline starting from 97900 has now formed two 30-minute centers, but the current downward cycle is at the 4-hour level, so the subsequent trend is very likely to upgrade the 30-minute center 2 into a 4-hour center through oscillation. Today, watch for resistance around the 5-day moving average 90800-91000, and support near 88000.

In terms of operation ideas, 1: Short near the 90700-91000 area, stop loss at 91500, take profit at 90000-89000. 2: Long near 88500-88000, stop loss at 87500, take profit at 90000-90500.
