This is a part of the bull/bear cycle, nothing to be afraid of, happens every few months and the point is to remain pragmatic about movements and capitalize on the fear in the market.
It seems people are always looking for reasons for every pump and dump which makes me to assume that they are not at all ready to understand the basics of bitcoin and the nature of a volatile market. In my opinion bitcoin market does not need any special news for pumping and when people book profits then it will have some corrections. So, rise and fall are just part of bitcoin market always.
