I don't understand how anyone can invest in anything without doing their homework. You work so hard for your money, much too hard to simply throw it away. I like to follow the Dev and get an idea of his vision for the future of his coin/token and if it is backed by a good project ot not. I prefer there to at least be some sort of main idea and reason for the coins existence.
Many ICO investors were early bitcoin/ether adopters. So they have crypto to spare. If they take a part of each pie, they could end up with even more profits.
I"m not saying it's smart or right. Just trying to get into their heads.
