1) What proof has been given that Bert Valkenborgs and Joeri Cornelissens are who they say they are?
2) Is there proof that the hardware apparently now hashing actually exists?
3) How are CryptX making money from this venture?
1, look at their linkedin profile and the sales history of cryptx. They are legit.
2, yes.

3, you already found your answer. Above that one of them is selling solarpanels, and the farm uses also solarpanels. So all we need for the farm is being brought to us by other companys that are owned by Bert or Joeri.
