PANews reported on September 21 that according to CoinDesk, the U.S. Securities and Exchange Commission (SEC) has filed lawsuits against three individuals and five companies, accusing them of operating a "pig killing" crypto scam. It is reported that the relevant lawsuit is the first enforcement action taken by the SEC against this crypto scam, just one day before the U.S. House Financial Services Committee is preparing to hold a hearing on the "pig killing" scam. Gurbir S. Grewal, director of the U.S. SEC's enforcement division, said in a press statement that relationship-based investment scams, including those involving crypto asset investments, pose a huge risk to retail investors, and this threat is increasing rapidly as these scams become more popular among scammers. In both cases, we accused the scammers of creating a fake crypto ecosystem and showing investors false information. Our charges remind the public to be highly vigilant about investment opportunities promoted by strangers on social media.
