Prediction (no sourcing, a guess) the Rosenstein announcement won’t be that exciting. Indictments for bitcoin or RICO, something financial. A major case normally but likely not huge Trump Russia, - obviously hope to be wrong!
Reason for this guess: no other major ostensibly Trump Russia announcements have been accompanied with press conferences. Again, could be wrong.
If there's child pornography embedded in #Bitcoin, that's huge in itself.
Holding Bitcoin would be possession of child pornography.
Getting rid of it to cut your losses would be trafficking in it for profit.
There are innocent people who need to know how to dump Bitcoin.
