IoT Chain and The Bee Token seem promising projects to me. I'm even considering buying a couple. However, note these, as well, as their profitability and potential cannot be denied:
1. LiveEdu -  the world's first education ICO. LiveEdu is building the world's largest project-based learning library, starting with the seven topics programming, game development, data science, design, VR & AR, AI and cryptocurrencies
2. Restart Energy -  the world's first Ethereum token able to virtually store electrical energy.
3. Cointed - their partnership with Nvidia and TAS Group enabled them into adopting green mining and launching multiple Crypto ATMs in Europe.
