A bomb threat where a person demands to be paid in dollars is not a "US dollar bomb threat"! A threat where someone demands to be paid in Euro is not an "EUR bomb threat"!
How come when somebody asks BTC it suddenly becomes "a Bitcoin bomb threat"? WTF is wrong with these news sites?
Hey, sites like this needs "Clickbait" articles to increase their views, so a juicy story like this is just what they need.
Also, let's not forget that people will use any "currency" for things like this, no matter what their goals is. They could have used cash dropoffs or even stolen bank accounts. This can even be the "masters" of our enemies, doing this to taint Bitcoin's image with the public.
We know what these people did with 9/11. Why would their tactics be any different with Bitcoin?
