BlackRock's head of digital assets, Robert Mitchnick, stated that despite the increasing number of complex structured crypto ETF products in the market, BlackRock will adopt a more cautious strategy. According to Wu's report, there will not be too much 'heterogeneous' innovation in ETF structures. BlackRock launched the Staked Ethereum ETF iShares Staked Ethereum Trust (ETHB) this week, with a first-day trading volume of approximately $15.5 million and a net inflow of about $43.5 million. Previously, its spot Ethereum ETF ETHA has accumulated an inflow of about $12 billion since its launch in July 2024, while the Bitcoin ETF IBIT has seen total inflows of over $63 billion since its listing in January 2024.
