According to Golden Finance, only 6 of the 13 applicants for Bitcoin spot exchange-traded funds (ETFs) have indicated how much management fees they will charge, and they are expected to be approved as early as next week, so this number has become a reality for potential investors to focus on. Although many factors determine the popularity and trading volume of ETFs after listing, in this case, all ETFs will hold the same asset (Bitcoin), so details such as cost become key differentiators.
