Very insightful. I've done the calculation and it seems that KNC Jupiter is still a pretty good investment.
Im still debating that, I looked at buying say 3 x Jupiter (I have one on order now) and still with all 4 the return with shipping dates from October doesn't seem worth it if you run the ROI calcs until they are no longer covering electric. I still think I am better of just holding bitcoins and waiting to see what happens. Thats just me though
