#数字资产市场动态 Bitcoin is fluctuating back and forth between $89,000 and $90,000, with bulls and bears fighting fiercely at this critical level. From the daily chart, the rebound strength is not yet strong enough, and it may be worth considering short positions around the 90,000-90,700 range. The support levels below to watch are 87,500 and 89,000; once these are broken, there could be further room for adjustment. Currently, neither bulls nor bears have an absolute advantage at this level, and the technical outlook still needs further confirmation.
