This fake news propogate by some people who want to crush Bitcoin just to buy it in smaller price.
I completely agree with you, however in the end of the day it comes down to the bitcoin users/holders. So just if the price drops by 8%+ do NOT panic sell the people who end up selling just create a snowball effect and cause the drop to sometimes double. However in some cases I noticed a few people selling just because they want to buy-in at a cheaper price which might seem like a risky move. I've been quite intrigued with the phrase "Buy the rumor, sell the news". TLDR: HODL and BODL
