Bitcoin rebounded after hitting a bottom around 91,800 yesterday, rising to near 93,000 before stabilizing. This morning, it retreated back above 92,000, and the bullish momentum has clearly weakened.

From the 4-hour candlestick chart, this rebound was suppressed around the 94,200-94,500 range—this level is not only the key 0.618 Fibonacci retracement point but also an area of previous high-density peaks. More notably, a double top pattern has already emerged on the chart. The Bollinger Bands are beginning to contract, with the price trapped below the middle band and facing downward pressure, while the MACD indicator has formed a death cross and a green histogram, indicating a clear bearish signal.

Based on the above technical analysis, it is considered that a rebound to 93,500-94,000 is a good shorting opportunity, with the initial target below at 92,500-91,000. Ethereum's situation is similar; a rebound to 3,325-3,350 can be considered for short positions, with targets at 3,250-3,200.
