Investors have retracted their fraud lawsuit against billionaire Elon Musk, which alleged deceptive practices related to Dogecoin promotion. The lawsuit claimed Musk used social media and influencers to drive a pyramid scheme but failed to provide sufficient evidence of financial wrongdoing. Initial damages sought reached $258 billion, but after four amendments over two years, the case was dismissed. Additionally, Donald Trump recently appointed Musk to head a new Department of Government Efficiency, coincidentally sharing an acronym with Dogecoin.
