You have no edge. Power costs for most miners are so low that it is not much of a factor.
I'm curious what hash rate you got for you $54,000. That will determine if you have an edge or not.
$54k is total investment after all Asic orders coming in, the last order from Cointerra won't come in until mid January.
Currently spent around $36,000, not all units are online, waiting for some PSU's as Butterfly's provided PSU's with their 60GH/s are a real fire hazard.. had one pop and smoke (not UL rated).
Projected Hash Rate in next week will be: 1,460,000 Mh/s
I think power costs would be significant for someone running Qty. 2 Jupiters, Qty. 6 60Gh/s Butterfly and one old Minirig
Minirig alone draws 17 amps of power.
