Well, what do you expect? SEC tweeting us warning about ICO, china banning ICO, its mostly just scam
In regards to the SEC, their actions show that it might be the opposite. If most of the ICOs are scams, the SEC would've gone after them or banned ICOs. In past years, the SEC has gone after much smaller deals worth a few hundred thousand dollars.
This is not to say that the SEC won't do this shortly. But one document from the SEC about one ICO out of the hundreds of ICOs, is not indicative at most ICOs are scams...unless the SEC does a lot more.
