ICO's are essentially securities so it makes sense for the SEC to crack down, and this second warning should scare off anymore so called "CEO's" from jumping into the craze. The funny thing is, most of these ICO's that aren't public companies have been the most successful. They're offshore and anonymous, leaving the SEC with their hands tied.
MGT has attracted a lot of money lately, most people see it as a much safer place to bet on mining. Do they actually mine? I'm still not sure. We'll see if McAfee actually does his ICO now, haven't heard much about it since he talked about it on twitter last month.
Also, I liked the part about the p&d's, pretty good concise explanation. Seems like common sense to me, but you know what PT Barnum says. Should be required reading.
