No one can predict future market conditions, if this can be done then they are just guessing, everyone just keeps buying because they hope the future price will improve, other than that usually people who like to guess don't do anything, just give guesses, I even followed several people who gave 2 guesses, namely the price will skyrocket and the price will decrease, if something goes wrong, the post will be deleted.
I also don't understand why you think like that, because not everyone who guesses does anything. I'm not even sure if you've done any research on those guessing except for a few people you've seen in person. After all, those who make price predictions are actually not guessing, but rather speculating on prices that have happened before even though this will not be completely accurate because prices always tend to change over time.
