$TRUMP In the past two days, it surged from 2.7 to 4, up more than 30%.

The reason is simple: the project team announced they would hold an "exclusive dinner for major holders," saying Trump himself might attend, and then the coin price went up.
It's "might" attend, the White House hasn't confirmed, and the project team itself left a way out saying if he doesn't come they'll issue NFTs instead.
In January, TRUMP coin launched at a price that surged from 1 to 75, when Trump had just taken office, which was a real hotspot. Now it has already dropped 96%, this rally to 4 dollars is still 94% away from the all-time high.
The 24-hour trading volume surged from tens of millions to 1.9 billion dollars, up 493%. This kind of abnormal trading volume usually means someone is cashing out.
The current pump is just another round of harvesting retail investors.
