Matthias Woestmann is also a CEO at Quadrat Capital for the last 14 years (https://www.linkedin.com/in/matthias-woestmann-b87922119/).
The domain age for Quadrat Capital is just over a year old though.

The history and obscureness of the people heading Envion is highly ambiguous. 

Great concept of being able to move where the costs are low. Blockchain mining companies in China like BitMain have cashed out massively with the boom of cryptocurrency values recently. They don't need any funding to adapt to sustainable and more powerful rigs so if Envion is a true company, their return on investments are highly optimistic.

Grain of salt here people.
