Maybe because people have made literally hundreds of thousands to millions of dollars holding/selling what you consider 'shitcoins.' Maybe it's because people have also made tons of money with futures and derivatives. Maybe instead of thinking that listening to what those you disagree with the way you think is pointless because you disagree, You could see it as a way to learn and gain knowledge and maybe find something useful to you in the process. But we all know the odds of that are virtually zero because as I said before you're literally like a toddler holding their hands over their ears saying "la la la i can't hear you." Anything that challenges the way you think is scary to you, isn't it? You were sheltered as a child weren't you?
