These discussion forums are strange. Each discussion consists of 30% sensible and thoughtful postings, interleaved with 70% idiot postings. I am getting used to this, but I still have to waste a few seconds on each idiot posting to recognize and ignore it.
Have the idiots still not lost all their money and disappeared? Many have, but new ones are always streaming in.
I would say 40% of it is deceptive, e.g. I'll tell everyone I'm holding BTC so they won't panic sell and I can get a better price for mine
Yes, quite possible. It could also be a mixture of stupidity and deception though, so 30% sensible information, 30% pure stupidity, and 40% stupidity mixed with an attempt to make others follow on the flight into the ground.
After the first bubble in 2011 many of the obviously stupid posters disappeared for good. Perhaps the same will happen here too.
What I never see is that those who posted their weird predictions now come back and say, "OK, I was wrong. Where was my mistake? How come you saw the future correctly, while I didn't?" Apparently these people are not really interested in learning. I guess they lose all their "investment", then they disappear and look for another place where they can do other stupid things.
