Despite once calling Bitcoin an "immature asset class" and deeming it unsuitable for long-term investors, Vanguard Group has now become MicroStrategy's largest shareholder. According to Bloomberg, the institution, which manages $10 trillion in assets, holds 20.00 million shares of MicroStrategy through its funds, accounting for 8% of the outstanding shares, and most likely surpassed Capital Group in the fourth quarter of last year to become the largest shareholder.
