This is a good speculation that could very well be true. Bitcoin is not essentially being devalued by it's customers, it's just that the price is going down due to more coin going into the flow‽
Along with some people devaluing it because the price is going down and they are confused.
But nobody cares about the traitors... lol
Yeah. Just the dumping of coin. In the last six months there has been steady good news on bitcoin - large scale merchant adoption, one after another. There has been, worldwide, "the light going on" in governments and their shills and their people about the existence of the virtual currency, it's goods and bads from their point of view.
That's all good.
So I'm going to say it's the coins stolen from the Silk Road userbase by the FBI, then sold at auction. At what price, $800+? Those were investors and they are likely all getting out.
