Recently, the digital currency trading platform and Exchanging BTC-e has been seized (you can check at http://www.btc-e.com/index.html).
That mean half of all Bitcoin are in the hands of authorities. They can decide whither the price will go.
As i see it (if it's true), it's the theft of of the century.
If someone have more information, please share. Let me know if i'm wrong or right
