Yes I agree with that but people must take responsibility also by investing on the basis of a tweet, but it can still be good, hey I got into bitcoin thanks to Raoul Paul and PlanB S2F, imagine that, among a few other things, even if planB chart was wrong in future price prediction it allowed me to see the bitcoin chart since the beginning (zoom out) and gave me confidence to get into bitcoin and to fall into the rabbit hole. Many also buy at the top with FOMO and then get forged by the bear market. Greed is almost always the first motivation.
