Golden Finance Report: Since the last filing with the U.S. Securities and Exchange Commission, the Wisconsin Investment Board has increased its investment in the BlackRock Bitcoin ETF. This move reflects investors' ongoing confidence and interest in the growth of the cryptocurrency market. As one of the world's largest asset management companies, BlackRock's Bitcoin ETF is attractive due to its compliance and scale effects. This investment not only demonstrates institutional investors' recognition of crypto assets but also further promotes the acceptance of Bitcoin and other cryptocurrencies in traditional financial markets.
