From a daily perspective, Bitcoin has been fluctuating between 84000 and 90000 in recent days, attempting to break through 90000 several times without success. This indicates that there is significant resistance around the 90000 mark, while the lower points are getting lower. Therefore, in the short term, Bitcoin's rebound should continue to focus on the 90000 threshold. Approaching this level is still not recommended for chasing the rise, and caution is advised against another surge followed by a drop.
