The U.S. SEC continues its fight against the largely unregulated crypto scene. The U.S. regulator sees many tokens as securities requiring registration and filed a complaint against the Dragonchain crypto scheme and its crypto asset, Dragon (DRGN). The SEC considers the Dragon to be a security, and, consequently, its issuance should have been registered with the SEC. Critics counter that the SEC has failed to issue clear regulatory rules for the crypto scene but acts via enforcement actions.
