Billionaire hedge fund managers are making significant investments in Bitcoin in 2024, even selling off high-performing Nvidia stock to do so. The launch of spot Bitcoin ETFs has been transformative, with nearly $20 billion flowing into Bitcoin this year. Bitcoin ETFs have amassed $52 billion in assets within eight months, exceeding expectations. Investment advisors are rapidly adopting Bitcoin ETFs, a trend highlighted by Bitwise CIO. Stanley has also joined in, allowing their advisors to pitch these funds. The real challenge remains mainstream acceptance and liquidity. MicroStrategy's Bitcoin strategy has notably outperformed every company in the S&P 500, including Nvidia, with its stock surging 825% since 2020. Michael Saylor, CEO of MicroStrategy, emphasized the success of their Bitcoin strategy, which has also outperformed Berkshire Hathaway. Saylor mentioned that he bought $8 billion of Bitcoin since 2020.
