ETH and Waves are not ICOs and have been on the exchanges for quite some time.

ICON and Wanchain are two ICOs that are extremely promising IMO but have already passed and are waiting to hit exchanges. Unfortunately I live in California and was unable to purchase either during the ICO, since they didn't allow US investors but I'm hoping ICON is released before the bitcoin fork, in which case the chances of picking some of cheap will be greater. Both are platforms with very promising teams behind them. Of course, do your own research before purchasing.
