Odaily Planet Daily News Bitwise Chief Investment Officer Matt Hougan said in a post that as of last Thursday (May 9), 563 professional investment companies reported having $3.5 billion worth of Bitcoin ETFs. As of the 13F filing deadline on May 15, we may see more than 700 companies with a total asset management scale of nearly $5 billion. This scale of holdings is unprecedented for new ETFs. Most ETFs attract only a few 13F applicants in the first few months of listing.
