According to BlockBeats, on April 23, Cboe BZX Exchange submitted a proposal to the U.S. Securities and Exchange Commission (SEC) to modify the previously approved Franklin Bitcoin ETF. Specifically, the deadline for cash subscription basket orders will be changed from 3 p.m. Eastern Time to 2 p.m., the exchange's regular trading closing time, or other time determined by the sponsor. The change is intended to provide fund sponsors with greater flexibility in determining subscription deadlines.
