I haven't heard about this but then I find it funny when people attribute one thing to another. Anyone who says price drop is because they want to dump their bitcoin is being stupid. They haven't seen a real market in their life.

Hell, he/she are they aware of the recent US sale of Silk Road's bitcoin. No one, and I mean, no one with such a huge cache is going to be able to sell coins without hurting themselves. Think about this if current value of their cache is say 60 million due to 600 USD per btc rate. Are they going to get same value when they try to dump? Obviously not.

The whole thing is simply, btctalk's favourite word, FUD.
