This early morning, Bitcoin and Ethereum both staged a "sharp rise followed by a pullback" show, and now they have entered a phase of slight fluctuation and sideways trading.
$BTC Bitcoin once surged to a high of 91190 in the early morning, then cooled off and retraced. Currently, the price is stable at 89600. From a technical perspective, it is stuck in the middle of the Bollinger Bands.
Above, the upper band at 89900 and the previous high are blocking the way, making it difficult to continue upward; below, the lower band at 89500 and today's low of 89160 are supporting it.
