From the four-hour timeframe, Bitcoin repeatedly encounters resistance at the middle band of the Bollinger Bands and pulls back. The rebound is only a technical correction, and the overall downtrend remains unchanged. The three Bollinger Bands are narrowing downward simultaneously, indicating a shrinking trading range and persistent bearish pressure. The one-hour timeframe further confirms a solid bearish structure, with the price quickly breaking below the middle band after a rebound, and the middle band continuously moving downward to form multiple resistance levels; the KDJ indicator briefly recovers but then forms a death cross again, indicating weak rebounds and that bearish momentum is further releasing. Bitcoin is advised to stay around 76700-77500🈳, with a target downside of 75000-74000. The auntie suggests shorting around 2280-2300, with a target of 2200-2100.
