even though there is positive news, but the negative news has a greater effect for now, the current price has started to improve, but I am afraid this is only a correction before continuing the trend
Yep, negatives news keep coming and we can't avoid those stuff. Hacking, terrorism, bad news about Bitcoin and stuff are the factors why Bitcoin falling down until now for more than 3 months.
There has been a negative news everywhere and the positive ones aren't being recognized because they were covered by these bad news that keeps coming.
And these news drives the prices down so whomever creating or paying these news to came out can take the advantage of packing more bitcoins on their storage and prepare for the upcoming recover which they are aware would come. While taking the effect, panic sellers are rushing to dispose their btc's thinking that there will be no more reversal.
