At the end of the day all ICO's will be regulated as securities by the SEC until proven that the given coin is fully decentralized. I feel like ICO's avoiding US soil are pretty much all conceptual coins and or are trying to scheme investors out of money and for the most part people seem to be getting tired\aware of those type of ICO's. The purchase of Keystone by Coinbase seems to be a move to be able to list more securities but still need regulatory approval. Overall it still seems premature but it never hurts to wonder
