Why is it said that the short-term trend of Bitcoin is downward?

This can be seen from March 2nd, when that evening Trump announced that Bitcoin would be used as a strategic reserve, causing a short-term surge of 10%. However, it quickly fell back down.

Why did it fall back so quickly? Because unexpected news does not change the existing market trend, which indirectly confirms that the short-term trend of the market is still downward.

Otherwise, such news would not lead to such weakness at the beginning of a bull market. So, everyone, just short at highs.
