SEC doesn't help us. It solves the problem of clear scammers. But people can spot them by themselves.
What sec really does is building walls for startups. In IPO it was a big problem to collect money by securities issue. And small startups with great ideas were not allowed to get money from investors. ICO made this barriers disappear.
And the main task of SEC is to block such startups so the market will enter only those projects that have money on this procedure, but they are already big companies, almost always.
