This time's rally is driven by Chinese, and whoever spread the FUD this time was a bit too western centric and it didn't manage to spread the FUD in China. FUD fail. FUDster can now watch the price keep going up and bite his cheeks for selling everything.
Hmm, so one theory could be this guy who published the article, was paid for by someone with deep pockets to buy in.
Chances are that it was just a sterile academic trying to make a name for himself.
If there's one thing I've learned - it's that paid shills do exist on the internet and in academic circles, and in significant number, as has been proven by multiple FOIA requests and leaked documents. But on the other hand, the supply of "useful idiots" is unimaginably greater! So the chances that these academics were actually paid to spread FUD is incredibly small. They were just like "Hey let's write about this attack on Bitcoin" without realizing that it has already been discussed and dismissed, 3 years ago, and even with its infeasibility, changes are continually being considered for future releases (and for miners themselves) that even further diminish its feasibility.
But really, it's amazing how many people read the article, believed it at face value without any further research, and are now quoting the article's introductory paragraph on ZH comments as if it is gospel and an eternal "debunk" of all things bitcoin. I would think these people should have learned their "Don't believe everything you read on the internet" lesson the first time they fell for an Onion article...
