NBA legend Shaquille O'Neal said he doesn't believe in cryptocurrencies and was merely paid to endorse the now-imploded exchange FTX, per a Thursday report by CNBC's Make It.The complaint, filed by investor Edwin Garrison, alleges that FTX used celebrities such as O'Neal, Curry, and fashion model Gisele Bündchen to attract investors to a Ponzi scheme, per court documents seen by Insider.The crypto world was shaken when FTX filed for bankruptcy on November 11, and as its new CEO John Ray reported a litany of gross mismanagement practices at the firm.However, he started teasing the idea of getting involved in crypto-related content in February, musing on Twitter that he could change his handle to SHAQ.SOL — a reference to a cryptocurrency run by blockchain platform Solana.The NBA hall of fame member did not disclose how much money he received for appearing in the June FTX commercial."
