for someone who as written so many books and was a CIo you think they would provide better explanations instead of blatantly dodging direct and simple questions as well as provide a little better Customer Service. 

I would like to know how his contract could be used against him.  it makes no claim of performance.  Just for giggles i made a spreadsheet to see how this would work out from their pov and mine given a 50% increase in difficulty every 10 days.  I understand thats a large padding.

If i had one of his miners go online for me on 11/5 the suretly amount would have paid by 12/25.  After that the income in $ would be $250 every 10 days and dwindling to $22 every 10 days by March.  Your contractual payments to them would be more than your income mid-January, and you are on the hook for 5 years of payments.  Nothing in that contract says when they will make upgrades and by how much.  I fear you may find yourself on the end of a losing battle.
