Probably fake news, people panic selling, people selling for profit then buying back when price is low.
That is happening often. Billionaires often abuse the news to scare investors with little experience. That would cause them to lose all their assets or lose a lot of money.

Whales have been abusing the power to scare investors away for a long time but it seems that people do not learn that is why they keep abusing the power and since people do not learn then the whales do not have any kind of reason to change and I cannot blame them if people keep falling for the same trick over and over again then there is no point in trying any kind of advanced tactics, they can keep doing what it works for them and get even bigger fortunes because of it while everyone else losses money.
