There is nuance here you are passing by. This is a classic influence pump and dump, these sort of scams make their rounds in various shitcoins all too often. It is a good thing you are hearing about them, because they are being caught. Don't fall for the survival bias fallacy. However, a well diversified index fund is not the same thing. If it seems the same, keep your money in a savings account and pay tithe to hopefully keep the inflation monster at bay.
