According to PANews, Bloomberg analyst Eric Balchunas has revealed that approximately 2,000 ETFs have been launched over the past decade. Among these, BlackRock and Fidelity's Bitcoin ETFs have secured positions in the top 10 based on total assets under management (AUM). Despite being introduced less than a year ago, IBIT and FBTC have quickly risen to become some of the youngest ETFs in the top 10.
