The US Securities and Exchange Commission (SEC) has announced additional proceedings to determine whether proposed spot bitcoin exchange-traded funds (ETFs) from BlackRock, Invesco, Valkyrie, and Bitwise should be approved. In letters regarding the Valkyrie Bitcoin Fund, the SEC asked for input from supporters and opponents of the proposals in an apparent delay to approvals for the funds. The SEC previously put confidence in the creation of such funds on hold in August of this year.
