PANews reported on September 28 that according to Decrypt, less than a year after its Bitcoin ETF was traded, BlackRock, the world's largest asset management company, increased its Bitcoin holdings to nearly $24 billion. Recently, BlackRock purchased another $35 million in Bitcoin and $6.4 million in Ethereum, holding a total of 357,737 BTC, accounting for about 1.70% of the total Bitcoin supply. In addition, BlackRock's Ethereum holdings have also increased to 350,000 ETH, worth about $989 million. As institutional investors' interest in cryptocurrencies increases, BlackRock and Grayscale's ETFs together hold nearly 3% of the circulating Bitcoin.
