According to Bloomberg's senior ETF analyst Eric Balchunas, Jay Jacobs, head of BlackRock's ETF department, stated at the 'ETFs in Depth' conference that current Bitcoin and Ethereum ETFs are just the tip of the iceberg, with only a small portion of clients holding IBIT and ETHA ETFs. He mentioned that the company will focus on expanding the coverage of these two types of ETFs rather than launching new altcoin ETFs. Additionally, Tidal's Mike Venuto indicated that there are frequent proposals for 'Bitcoin + other assets' combination ETFs and expects future ETF strategies to be linked to assets like Bitcoin, NVIDIA, Tesla, and MicroStrategy.
