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.
As far as I know, a Korean exchange has stolen a lot of bitcoin and altcoin assets by hackers. since they posted this information online and many were scared to sell bitcoin at low prices to retreat from the market
