Today in the market, Bitcoin has been fluctuating within the range of 90600 to 91700 with narrow oscillations, and the overall momentum appears somewhat weak. From a technical perspective, upward momentum is clearly lacking, while downward pressure is gradually building. This pattern is not very friendly to the bulls.

Looking at the hourly Bollinger Bands indicator, the problem becomes evident. The upper and lower bands are continuously converging, while the upper band and the middle band are still diverging downward, forming a suppression effect. Although the lower band shows some signs of curling upward, the strength is insufficient, and support is limited. The price has attempted several times to break through the middle band’s resistance but has been pushed back each time, remaining below the middle band. This characteristic of "rebound then facing resistance" clearly indicates that the short-term market is dominated by bears.

Regarding specific trading strategies, it is recommended to watch for short positions around 91700-92500, with targets in the 90000-89300 range. For Ethereum, consider shorting between 3200-3240, with support levels at 3090-3040. Also, pay attention to the correlated performance of main cryptocurrencies like SOL, XRP, and BNB, as they tend to follow the overall market trend.

Overall, the market currently lacks the momentum for a breakout, and rebounds are being suppressed. Under such a pattern, it is advisable to remain cautious and focus on defense.
