Hello guys ,
I am just thinking of it at the moment , I have a spare place and electricity cost is about 0.02 usd for the first 128KHw and then 0.04USD per Khw .
I am thinking of getting Spondoolies SP31 X2 to reach 9TH/s . According to my calculations I would make about 18.5 USD per day not taking in account the equipment cost , can you correct me if I am wrong ?

I am just new to mining and bitcoin and just working it out if is good or bad investment . But I live in Algeria and price of electricity is :0,017 euro for the first 128 kwh then 0,038 euro after which is about 0.04 usd .
