Bitcoin, after reaching a high of $89,450 in the previous trading day, began a correction. It stabilized after touching a low of $84,400 yesterday morning, then entered a sideways upward channel. As of the late trading session yesterday, the price tested a high of $89,360, just one step away from the previous high. However, the $90,000 psychological level faced clear resistance, leading to a slight pullback during the evening session, with the lowest point touching around $86,800. It then rebounded again to above $88,000 for consolidation. From a technical perspective, with the weekend approaching, market trading sentiment is likely to become more cautious, and the fluctuation range is expected to narrow further. On the weekly chart, Bitcoin remains in a high-range narrow oscillation, with no clear breakout signal; on the daily chart, it moves within a narrow range between the lower and middle bands, with the current price closer to the middle band relative to the range. Overall, Bitcoin continues to test higher levels amid sideways movement, showing a mildly bullish trend. The daily momentum for a decline has weakened, and although there are signs of resistance near the middle band, the core rhythm of sideways upward movement remains intact.
