Information for the fourth day of trading spot Bitcoin ETFs in the US has been fully collected. Once more, the figures are remarkably outstanding. Eric Balchunas, an analyst at Bloomberg, shared the latest information for the fourth day concerning spot Bitcoin ETFs traded on Platform X, pointing out the robust results of the recently sanctioned spot Bitcoin ETFs. This group, dubbed the “Newborn Nine,” consists of all 10 approved ETFs with the exception of Grayscale, which transformed its GBTC Trust into an ETF. Two Bitcoin ETFs centered on spot pricing are among the top five most successful launches in terms of assets under management. Balchunas reported on the rapid growth of these ETFs, stating, “The fourth day showed significant progress, with the ROLLING NET FLOWS reaching +$813.953 billion, thanks to the Newborn Nine attracting $914 billion on Wednesday, marking their strongest day so far, which overshadowed the $450 million withdrawal from GBTC.” The ‘Nine’ have currently amassed $3 billion and conducted transactions amounting to $243 billion within an unusually high first four-day period. The surge in capital injections has especially benefited BlackRock’s IBIT, accumulating more than $237 billion. Meanwhile, while significant sums have also flowed into Fidelity’s FBTC, with $2.256 billion, and Bitwise’s BITB with $436.75 million, both still lag behind BlackRock’s fund. Bitcoin exchange-traded funds experienced these investments on day 2247, according to information from Eric Balchunas. The strong expansion of these ETFs doesn’t just represent the transfer of investments from Grayscale’s GBTC.
