The U.S. Securities and Exchange Commission suspended trading in QMMM Holdings after the company’s shares surged more than 2,000% in September. The regulator cited concerns of possible manipulation tied to social media recommendations by unidentified parties. QMMM, a Hong Kong-based digital advertising firm listed in the U.S. through a Cayman Islands structure, recently announced a $100 million cryptocurrency treasury. The plan includes purchases of Bitcoin, Ethereum, and Solana, positioning the company within the fast-growing digital asset sector.
