I think the title is a little aggressive - it presupposes that an ICO buyer received a "tip" with inside information. While that's not an unreasonable thing to consider with respect to an angel (or larger) investor who has substantial contact with the company/people behind the ICO, arbitrary retail-level speculators who are just throwing money at anything using the word "blockchain" or "ICO" aren't likely to be punished by the SEC for having too much information.

Instead, they'll be punished by the market for being idiots. But that's a different sort of thing.
