The recent PC Word article described Bitcoin as a "decentralized virtual currency". I believe the description would have been more correct if the term used was "digital currency", as Bitcoin's FAQ describes it.
I then read about Facebook Credits which were labeled as "digital currency".
http://www.variety.com/article/VR1118028888?refCatId=1009Facebook Credits can accumulate but funds are one way, they can only be spent within facebook (e.g., on e-cards and for Farmville Cash).
Is this a mis-use of the term digital currency, or is there a blurring of the line between the two.
