Investors launch class-action lawsuit against SafeMoon, alleging it used celebrities to 'pull first, then smash'
A new class action lawsuit calls for a jury trial of top celebrities and socialites for their alleged involvement in a “pump and dump” scheme involving SafeMoon tokens. SafeMoon claimed to have recruited celebrities to lure investors with misleading publicity. Some of the big names in the class-action lawsuit include musicians Nick Carter, Soulja Boy, Lil Yachty, and YouTubers Jake Paul and Ben Phillips.
According to the lawsuit, SafeMoon and its subsidiaries mimicked a real-life Ponzi scheme, misleading investors into buying SafeMoon tokens under the pretext of unrealistic profits. They claim the ecosystem’s “burn” and “token economics” are key drivers of SafeMoon’s price potential, and the celebrities allegedly persuaded their fans to invest in the token.

Additionally, the lawsuit points to numerous examples of celebrities who have successfully hyped the token and artificially pumped it up. While SafeMoon had grown several times over the course of a few months, the company's top executives left abruptly, at which point the token's price began to plummet. (Cointelegraph)
