The Securities and Exchange Commission (SEC) has charged music producer DJ Khaled and boxer Floyd Mayweather Jr. with promoting investments in initial cryptocurrency coin offerings without revealing that they had been paid.

The stock market regulatory authority on Thursday said that cryptocurrency coins sold in initial coin offerings (ICO) may be considered securities and subject to federal securities laws, reports CNN. 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, it said.
