The Securities and Exchange Commission has halted trading of a company after its stock boomed by over 2,000% following a recently announced crypto treasury pivot. Digital advertising firm QMMM Holdings earlier this month announced a plan to buy Bitcoin, Ethereum, and Solana—causing an explosion in the price of its stock. In September alone, its price has risen by more than 2,100%, according to Yahoo Finance data, finishing Friday at a price of $119.40.
