In a comparison between asset management giants BlackRock and Vanguard, BlackRock emerges as potentially more appealing to cryptocurrency enthusiasts. While both firms offer a diverse range of investment products, BlackRock has notably launched Bitcoin ETFs, a move Vanguard has yet to make. As of March 2022, BlackRock commanded a 34.6% share of U.S. ETF assets, with Vanguard trailing at 29.2%.

BlackRock, the world's largest asset management firm, manages $9 trillion in assets under management (AUM) as of 2023. Its largest ETF is the iShares Core S&P 500 Trust, with over $464 billion in AUM.

On the other hand, Vanguard, the world's second-largest asset manager, manages $7.6 trillion in AUM as of 2023. The firm is synonymous with passive management and strong diversification through index funds.

Despite the differences, both BlackRock and Vanguard offer competitive low-cost index funds, with little difference in comparable ETFs. However, BlackRock's foray into cryptocurrency could sway investors looking for exposure to this asset class.
