Let’s set the stage… Bitcointalk is being DDOS’d, and has been down since this morning. Gox is experiencing 15-20 min lag on the trade engine. A hoax about all bitcoin private keys being leaked is making the rounds (and apparently, fooling some of the newbies). Price is at $850 on gox as I’m writing this.
All signs point to serious market manipulation by someone looking to pick up bitcoin on the cheap. Selling now would be foolish. Turn your computer off, and go do something else. Everything will be fine.
Expect a rebound to over $1000 within the next 24 hours.
