A couple things make me suspicious of this report.
1) It would be odd that they would just approve the Blackrock iShares ETF. The thinking is that they would approve a bunch at the same time, like they did with the ether future ETF.
2) A Fox reporter now says she's spoken to Blackrock.
3) The gains have now faded.
