#数字资产市场动态 Yesterday, Bitcoin rebounded after touching a bottom near $88,465, ultimately facing resistance and falling back at $89,908, maintaining narrow fluctuations throughout the day. Ethereum also found support at $2,904, followed by a corrective rebound, performing well with a high-altitude strategy.

From the daily chart, although Bitcoin rebounded briefly, its continuation is clearly insufficient, and the bears still hold the dominant position. The four-hour chart reveals more issues—price repeatedly oscillates below the middle band of the Bollinger Bands, which has been suppressing the trend. The KDJ indicator's three lines are heading downward, indicating resistance to a short-term rebound. The overall rhythm is that the market is repairing itself, but the bears are regaining advantage, with obvious selling pressure above.

Based on these signals, early trading should mainly focus on short positions. When Bitcoin rebounds within the 90300-91100 range, consider establishing short positions, with support levels at 88800-87200 below. For Ethereum, short positions can be taken during rebounds between 3000-3050, with targets at 2910-2810. The subsequent trend of $BTC remains to be closely watched at these key levels.
