They just scroll it. And do you know who they are? The Chinese. The Chinese are the ones fueling the ICO craze. How do I know? I'm hanging out in a Slack channel full of them. I asked them how did you get into crypto? Verbatim response was that "friend said it easy money". Then he said "China full of money." Full of money indeed.
In fact the majority of ICOs are not even open to Americans.
