Music producer DJ Khaled and boxer Floyd Mayweather Jr. were charged by the Securities and Exchange Commission Thursday with promoting investments in initial cryptocurrency coin offerings without revealing that they’d been paid.

The SEC has said that cryptocurrency coins sold in initial coin offerings may be considered securities and subject to federal securities laws.

Both Khaled and Mayweather settled with the SEC and agreed not to promote any securities, even digital ones, for two years and three years, respectively. They also agreed to give back the money they’d received to the SEC and pay penalties with interest.

Mayweather failed to disclose that he’d received $300,000 from three different ICO issuers, including $100,000 from Centra Tech. Khaled failed to disclose a payment of $50,000 from the same company.

Both Mayweather and Khaled promoted Centra’s ICO on their social media accounts. Khaled called it a “game changer” while Mayweather encouraged his followers to get in on the ICO, saying he’d taken part.

Mayweather also commented on another ICO, saying he was going to make a lot of money.

The SEC, which has made it clear that ICOs can be fraudulent, encourages would-be investors to be wary or avoid those ICOs that are endorsed by celebrities.

“With no disclosure about the payments, Mayweather and Khaled’s ICO promotions may have appeared to be unbiased, rather than paid endorsements,”

“Social media influencers are often paid promoters, not investment professionals, and the securities they’re touting, regardless of whether they are issued using traditional certificates or on the blockchain, could be frauds,” said Steven Peikin, the SEC’s enforcement division co-director.

According to The Daily Beast, “This is the first SEC case pursuing violations over coin offerings,” which makes Khaled and Mayweather Jr. a pair of alleged crime trailblazers.

As Stephanie Avakian, the co-director of the SEC’s enforcement division, said in a statement today, “These cases highlight the importance of full disclosure to investors.” She added, 

“With no disclosure about the payments, Mayweather and Khaled’s ICO promotions may have appeared to be unbiased, rather than paid endorsements.” 

I think when everyone heard the news, no one was too upset. Looks like Mayweather will have to line up another fight soon enough.
