I liked an ICO which ended recently. But it was a unique and purposeful project dedicated towards curbing cryptocurrency exchange hacks. The project is called
https://incodium.io/. It is an API based Smart Contract Solution For Exchange Hacking. A risk management protocol that implements fast and accurate compensation functions on behalf of investors who are victims of an exchange hacking incident.
Excellent selection of promising project. Now there is really very little ICO with the finished product and who are really going to fulfill their promises.
