The world's leading asset management company, BlackRock, has achieved a new record in the market capitalization of its Bitcoin spot ETF products, surpassing $21 billion. This accomplishment signifies a growing interest among investors in the cryptocurrency sector, particularly for mainstream institutional investors, as it is a significant signal that the choice of Bitcoin as an asset allocation option is increasing within the market. BlackRock's Bitcoin spot ETF allows investors to participate in Bitcoin investment through traditional financial market methods, providing a more convenient and compliant pathway. As more major financial institutions like BlackRock venture into the cryptocurrency field, the market is expected to further attract the attention of both institutional and retail investors, driving the overall development of the cryptocurrency market.
