According to Odaily, BlackRock's U.S. Thematic and Active ETF Head, Jay Jacobs, emphasized the company's current focus on Bitcoin and Ethereum during the 'ETFs in Depth' conference. Jacobs noted that their exploration into these cryptocurrencies is just beginning, describing it as 'the tip of the iceberg.' He highlighted that only a small number of clients currently hold Bitcoin (IBIT) and Ethereum (ETHA) ETFs, which is why the company is concentrating on these areas rather than launching new altcoin ETFs.
