Bitcoin rapidly surged from around 90,000 within 1 hour to approximately 91,600, recording consecutive bullish candles. The short-term increase exceeds 2.6%, and the bullish momentum is being released rapidly. The technical indicators have entered a clear overbought zone, highlighting the need for a correction and repair.

At the same time, the current price significantly deviates from the MA7 and MA30, with the price far from the short-term moving averages. There is a strong technical need for mean reversion correction, and a subsequent pullback is highly probable.

If this rally cannot be sustained with continued volume support, it will form a divergence pattern of "price rising with decreasing volume," further confirming the weakening of bullish momentum and becoming a key catalyst for a bearish trend.

Bitcoin: Short at 91,500-92,300, target 90,500-88,500

Ethereum: Short at 3,160-3,210, target 3,050-2,960
