Ilon Musk and his companies Tesla Inc. and Space Exploration Technologies Corp. (SpaceX) are facing a $258 billion lawsuit over their promotion of the Dogecoin cryptocurrency, Bloomberg reports.

The plaintiff, Kate Johnson, claims that Musk and his companies created a fraudulent scheme to inflate the value of Dogecoin.

“Defendants falsely represented that the Dogecoin cryptocurrency was a sound investment, even though it had no value at all,” reads the lawsuit filed in Manhattan federal court.

Johnson, who claims to have “lost money due to the crypto pyramid scheme created by the defendants,” expects his lawsuit to become a class-action lawsuit and be joined by others who have also lost money on Dogecoin trading since April 2019.

In addition to damages, he wants the court to prohibit Musk and his companies from promoting Dogecoin.

The cryptocurrency, created in 2013 in honor of the Doge internet meme featuring a Shiba Inu breed dog, was trading at $0.057 on Thursday, down 67% since the beginning of this year. Last year, the value of Dogecoin was as high as $0.74.

Musk has previously said that Tesla and SpaceX will sell their merch for Dogecoin. In January, he suggested McDonald”s start accepting the cryptocurrency, tweeting (SPB: NYSE:TWTR) that he would “eat a Happy Meal on TV if McDonald”s accepts Dogecoin.”
