$BTC The current four-hour cycle trend of Bitcoin shows a clear characteristic: a rebound market with three consecutive bullish candles is significantly under pressure at the middle band position of the Bollinger Bands. The subsequent brief pullback and local warming did not reverse the overall weak trend. Considering the previous downward trend and the downward opening shape of the Bollinger Bands, the bulls lack the sustained momentum for an aggressive attack, making it difficult to effectively break through the key resistance around the middle band. The overall market pattern remains biased towards a bearish tone.
