Not sure.. Well.. maybe they wanted to use something which do not require physical contact or personal information.
They pretty much control huge part of land, you can say they've got their own country. I don't think they'd be concerned about physical contact or personal info. And as per article, they would use bitcoin to raise USD (or other fiat).
I hope most people will see right through those bullshit news. Couple of comments from the RT site:
come on, even a kid knows US and saudi was funding ISIS for a long time, just until ISIS got hold of that oil fields. I don't think they have time to sit around the computers and look for bitcoins to come in Just so they can buy that new nissan car and AK 47. A surprising news would be "ISIS commanding officer decides to come out and ITS OBAMA!!!" now That, IS a news
It's ALL about keeping the petrodollar and getting rid of Bitcoin which is a serious threat to the central banks . I knew that they would pull these lies out of their demonic little think tanks .
So bitcoin is being used to fund terrorists that USA setup to get rid of Assad? Well USA shouldn't have setup ISIS then?!
