This was not a question and let me give the possible reason. There is no major negative news and thus it is not because of it. There are next gen of ASCIs which had made mining easier. These are being tested by some pools and cost of mining btc is reduced because of this. They can thus sell for less and thus prices have reduced.
I do not know what the exact reason is, but it seems bitcoin is off by the media. Most people sell bitcoins at low prices because they are following the market trend. If the down trend, everyone sells to wait for price low and they will buy
