The U.S. Securities and Exchange Commission (SEC) is opposing Richard Heart's attempt to dismiss a $1 billion lawsuit. The SEC alleges that Heart defrauded investors through unregistered securities, including Hex, PulseChain, and PulseX. Heart, the founder of Hex, argued that the SEC lacks jurisdiction over him due to his overseas location. However, the SEC contends that his U.S. promotions and alleged misuse of $8.9 million justify their case proceeding.
