I do agree with some people's arguments or opinions that it is part of greediness and panic.
It drives us to think that we need to sell it a little bit higher again and again, and when the price hits the target, we continue again, to lengthen the target, and unfortunately the price drop.
And it drops down already, we are panic and they sell it.

The part of panic selling is also happening right now. People become panic when the price rise up and drop down so easily.
