On Wednesday an FTX investor sued Bankman-Fried as well as several celebrities who have endorsed the platform, including Tom Brady, Gisele Bundchen and Steph Curry. “The deceptive FTX platform maintained by the FTX entities was truly a house of cards,” the proposed class-action lawsuit states.

Lawyers Adam Moskowitz and David Boies filed the suit on behalf of an FTX customer, Edwin Garrison.

Moskowitz, a Florida lawyer, is also behind a class-action suit against crypto broker Voyager Digital, which also filed for bankruptcy earlier this year. And Boies is perhaps best known for representing Vice President Al Gore in 2000’s Bush v. Gore.

In an email to CNN Business, Moskowitz alleged FTX was “a massive Ponzi scheme larger than the Madoff scheme.”

“FTX were geniuses at public relations and marketing, and knew that … [it] could only be successful with the help and promotion of the most famous, respected, and beloved celebrities and influencers in the world,” Moskowitz wrote.
