Envion "Team"...As an old man with some wisdom and experience I must say that there are more questions left unanswered than I see with other ICOs and it seems your lack of transparency is your Achilles Heel. This market is built upon full transparency and while I was tempted to invest in the beginning, the following gaps will cause me to stay on the sidelines...

1. Zero transparency on founding team
2. Invitation to Berlin to see MMU but then saying you don't want to disappoint visitors with unit offline
3. No video of operating unit
4. No live mining data or metrics, again not wanting to disappoint with inoperable MMU
5. Promises of notarized LOIs prior to ICO, then saying it won't happen until after
6. Depending on older technology while supplies are limited on newer technology...danger of being obsolete out of the starting gate and not being able to meet production goals in manufacturing AND mining
7. My gut...and as an employee of one of the most innovative data center companies in the World, my gut is educated on green energy

Bottom-line...there are just too many gaps in your story
