After the short-term dip, a rebound signal has appeared. Within 16 hours, 91,550 is the key dividing line: a breakout above this level could establish a trend reversal, while caution is advised for a black swan crash risk during pullbacks.

In terms of operations, BTC can be lightly bought around 88,700-89,000, with a stop loss below 88,500; ETH can be simultaneously positioned, entering on a pullback to the 2940-2970 range, with a stop loss set at 2900, and initial targets of 3050-3100.
The previous support at 90,000 has stabilized and rebounded, but subsequent strength depends on closely monitoring the key resistance levels.
