I think it's a great ICO! Investors would be stupid not to invest.

My reasons:
1. They have built a working prototype. You can view videos of the prototype on their website and Facebook page. They did a Facebook live a few days ago, in which they did a complete walkthrough of one of the mining containers.
2. There is great interest in this project. The ICO is due to start only on 1 December 2017, and the Telegram group is already 2700+ members strong.

I am still waiting on their detailed ROI calculation sheets, which they mentioned will be made available in a few days time.
