probably become stable for a while around $4, there is a pretty sizeable bid wall there.
I agree, it should stop dropping around $4, as that is the cost for most people to produce them.
I do not think it was lowly miners causing the price to drop. It was people with massive amounts of
money that bought BTC or cheaply bought BTC (early adopters) that decided to just dump it all.
Miners do not all sell 15000K at once.. in a one hour period.
Larger players wanted out.
