Last night, BTC experienced a flash drop, quickly breaking below the 1-hour Bollinger Bands and parallel channel support. It is currently pulling back to the midline for confirmation.

The long-term downward channel structure remains intact. In the short term, it's suitable to try short positions with tight stop-losses, while closely monitoring the effectiveness of support at the 90,000 level.

Consider shorting BTC around the 92,500-93,000 area, with downside targets at 91,000-90,000.
