The most people are just spreading other people's passwords everywhere, posting about the ones that go up, pretending to be dead when they fall.

Acting as if they really have positions themselves 😂.
It's truly just to attract attention, but unfortunately most people believe it.
People with good character will feel embarrassed when they lose money, apologize, and then quickly run after getting back to break even.
People with bad character just pretend to be dead; if they make a profit, they'll boast about how awesome they are, and if they lose, they'll suddenly die and never mention it again 🙃.
