A federal judge dismissed a proposed class action lawsuit on Wednesday against Ethereummax’s founders and the crypto project’s celebrity endorsers, including reality TV star Kim Kardashian, boxer Floyd Mayweather Jr., and former Boston Celtics star Paul Pierce.

In his ruling, Judge Michael Fitzgerald of the U.S. District Court for the Central District of California agreed that the lawsuit’s claims raised legitimate concerns about “celebrities’ ability to readily persuade millions of undiscerning followers to buy snake oil with unprecedented ease and reach.” However, he explained:

While the law certainly places limits on those advertisers, it also expects investors to act reasonably before basing their bets on the zeitgeist of the moment.
