I think bad news sells better than positive news. Most of this negative news aren't accurate or correct. That notwithstanding, cryptocurrencies are Hot Topics and the media will want to leverage this to sell.
But I noticed more that those bad news affect the market a lot than good news because people are panic selling and other instances happen. That is, it affects a lot, but in Forex, all of the news is significant, which is why people really read a lot of news. In cryptocurrency, there are only instances, but still, it affects a lot in the market.
