The Securities and Exchange Commission on Monday filed charges against a U.S. citizen it alleged raised more than $1 billion through the unregistered offer and sale of crypto securities before pilfering millions to fuel a high-status lifestyle and the acquisition of luxury goods, including the largest black diamond in the world.

Richard Schueler, also known as Richard Heart, operated three crypto-asset offerings: Hex, PulseChain and PulseX. The SEC alleged he touted the investments as a “pathway to grandiose wealth.”
