$BTC Bitcoin night operation strategy maintains a bearish outlook, with key resistance area focusing on 88000-89100. If the rebound cannot effectively break through this range, it is expected to test the support near 86600 again. Once 86600 is lost, the current rebound will end, and the market is likely to further look down to the 85000-84000 area.

Ethereum is currently experiencing weak rebound strength, overall in a range consolidation. Key attention at night should be on the 2970-3020 resistance range; if the rebound does not break this, it is considered weak. The primary support below is at 2880, and if broken, it could look down to around 2800. Long positions are advised to wait for a pullback to the 2700 area before considering layout. If the night rebound unexpectedly breaks through the 2980-3020 resistance zone, the upper space is expected to open up to around 3100, and those holding short positions need to closely monitor the breakout situation of this resistance zone and adjust strategies in a timely manner.
