I guess Blacklist & the "Good wife" are the only series that mentioned Bitcoin .

That's weird this list doesn't include The Blacklist. Maybe because it was talking about a BTC IOU on the ripple distributed ledger 😉

There was another Blacklist episode where an assassin was paid using Bitcoin.Can't quite remember which season it was.

Yes it was Season 3 episode 5.
You can see it here https://en.wikipedia.org/wiki/Arioch_Cain

Yes, that's the one!
The bounty for the assassin was over 2,000BTC if I remember correctly.
