I filled some numbers into mining calculator and it's true that current ASICminer TUBE with gen3 chips will become obsolete in just one month from now? Do we have like 60Ph of these ? ? ?
Oh, you filled in some numbers on a mining calculator did you? What number did you use for the price of the miners? Let me take a quick guess - the retail price? What number did you use for power costs? 0.15 $/kWh?
Now, can you tell me the problem with that scenario?
Price of miners : 100$
Power costs : lower end what Friedcat said, so 0.12 $/kWh
delivery cost : 0$
setup cost : 0$
maintain cost : 10$/month
diff rise : 10%
and still you are unable to even break-even that 100bucks, retail price is four times more, any more questions?
