Boxing champ Floyd Mayweather and music impresario DJ Khaled on Thursday became the first celebrities to face punishment over their roles in touting cryptocurrency deals that regulators say were fraudulent.

Mayweather was paid $100,000 to endorse a coin offering promoted by three men who now face civil and criminal securities-fraud charges. DJ Khaled was paid $50,000 to promote the same digital coin, known as Centra, according to the Securities and Exchange Commission.
