$TRUMP These past two days have 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 possibly attend, and then the coin price shot up.
It's "possibly" attending, the White House hasn't confirmed it, and the project team themselves left an exit route saying if he doesn't come they'll issue an NFT instead.
When TRUMP coin launched in January, the price jumped from 1 to 75, right after Trump took office—that was a real hot topic. Now it has already dropped 96%, and this rally to 4 dollars is still 94% away from the all-time high.
24-hour trading volume surged from tens of millions to 1.9 billion dollars, up 493%. This kind of abnormal trading volume typically indicates someone is dumping coins.
The current pump is just another round of harvesting retail investors.
