#数字资产行情上升 Looking at the 4-hour K-line of $BTC, it's currently stuck at the 90500 position with repeated grinding, closely hugging the lower band of the Bollinger Bands and probing back and forth. The Bollinger Bands setup is interesting — the middle band is moving downward while the upper band is drifting upward. This widening pattern typically indicates that bears are still in control, and there's likely more downside exploration space below.

Looking back at this market segment, Bitcoin surged from around 94700 and then started adjusting downward across the board. After breaking below the middle band, it accelerated in weakness. Although there were several rebounds in between, the overall trend didn't change. Looking at the K-line combination, it's clear that bearish candles significantly outnumber bullish ones, and their bodies are quite substantial, indicating that bears have been exerting force during this period.

However, there's a detail worth noting: the volume of recent bearish candles has clearly contracted, and the pace of decline has slowed considerably, suggesting the market may be entering a consolidation phase.

The subsequent operational logic depends on how the 90000 round number level performs. If it gets broken, we need to watch whether the 89000-88500 zone provides support. Conversely, if 90000 holds, a rebound toward 91500 isn't out of the question. At the same time, don't forget to closely monitor Ethereum — the 3100 level is a key reference for short-term bull-bear negotiations.
