You're not supposed to think the CIA does much. They're the actual spy agency; the whole "just a star on the wall at Langley" thing is CIA; you don't hear about their victories, and if you do, it's a failure of some kind. Stuxnet, for instance, was almost certainly CIA.
If Bitcoin is a targeted strike against China somehow (not completely impossible), then the CIA is the likeliest candidate. Otherwise, of the USGov national agencies, the NSA is most likely.
The FBI doesn't really get anything out of it. The only reason I can think of for the FBI to do it is for paying off informants anonymously. (And as I've pointed out before, if anyone's an expert on money laundering, it's the FBI.)

I would believe NSA before CIA. The FBI gets involved in the internet space, but it doesn't seem like the CIA does all that much.
