I, too, can feel that the ICO in crypto world is in a big hype. My account in 21.co sometimes will get paid email from so-called new project or ICO. With only one or two paragraph, often meaningless. Maybe ask you to fill up a simple questionnaire which I doubt will give them any useful information. They just want to do marketing for their "ICO." And they pay 10 or 20 dollars for just a simple reply. That was the way the use money!
