Single
Cost of 1 unit = $599 @ 832 megahash/s @ 80 w/h
Cost of electricity per 1 unit per year = 700,800 watts or 700.8 kilowatts x 0.055 cents(price of electricity) = $38.544
Cost of operating 120 units or 100 gh/s x 38.544 = $4,632.69
Production Goal = 100,000 mh/s or 100 gh/s
Profits per 1 year based on 120 units or 100 gh/s = $127,239.312500
Cost of machine per megahash = $599/832 mh/s = 0.71 cents per mh/s
In conclusion. Lower cost of 1 unit(and total units) and lower electrical usage per 1 unit(and overall) per year. Higher cost of operating 120 units at $4,632.69.
RigBox
Cost of 1 unit = $29,890 @ 50,400 megahash/s @ 2500 w/h
Cost of electricity per 1 unit per year = 21,900,000 watts or 21,900 kilowatts(or 21.9 megawatts) x 0.055 cents(price of electricity) = $1,204.5
Cost of operating 2 units or 100.8 gh/s x 1,204.5 = $2,409
Production Goal = 100,000 mh/s or 100 gh/s
Profits per 1 year based on 2 units or 100 gh/s = $127,239.312500
Cost of machine per megahash = $29,890/50,400 mh/s = 0.59 cents per mh/s
In conclusion. Higher cost of 1 unit and higher electrical usage per 1 unit per year. Lower cost of operating 2 units at $2,409.
