Warning: The video is very uninformed, otherwise nice graphics and good description of that that Bitcoin uses digital signatures, they got that right at least. How can they do this wrong when BTC was worth 70 USD, to believe that each block is worth 50 Bitcoins.
They didn't do their research. On second thought don't watch it. I've watched it. I think it's bad journalism, also showing my fear that they don't do their research, before publishing stuff. techgear.gr -1
