it's been widely said that yesterday's dump was due to the goldman sachs rumors. the fact that they're now calling it "fake news" yet price hasn't recovered at all should tell you---the dump wasn't because of news. it was just the market being a market. price meandered weakly into a major resistance area ($7500) and bears sold into it. enough said.
It wasn't, but it also helped to spread the panic, so if some noobs have sold due to believing in this fake, it has turned into a self-fulfilling prophecy. And the price hasn't bounced back, because even if those noobs have realized that the news were fake, they still might be too anxious to buy.
But the effect of the news was pretty small, maybe -$100 out of ~$900 that were lost, majority of the drop came from normal volatility. It's not even that some whales and manipulators crash the price, if I were actively trading, I'd be selling these bull traps too (which I do occasionally, but with small amounts), to buy back more during the dip. No matter how much these "experts" predict the bull run, we are still in a bear market.
