Make sure to do your own research on the team behind that ICO.

I can suggest one high potential ICO though. Perhaps one of the most debated points with regards to blockchain technology today is the energy consumption issue. Last year, it was declared that the Bitcoin consumes energy as much as was used by over 159 countries! Good thing that NeuronChain comes into the picture as they are an environmentally responsible company. You can check their website here: http://neuronchain.io/
