Spreading false information to cause a decrease in value of bitcoin so they can buy it in lower price and sell it when it increase again. Typical tactics.
Yes that's true, this is the wrong doing most of the whales in crypto, they spread FUD and fake news to crypto and some bitcoin holders fall to their tactics and sell their holding at the very low price.
But for me I just hold my bitcoin whatever fake news show-up, I know bitcoin is a solid one.
