I really do not see why anyone would make another person run his/her GPU mining equipment . First of all the process of setup your own GPU's rig is pretty easy + when he/she want to cash out money they do not need to wait for a full month . With most mining pools you can cashout every day if you want . the only thing you have is low electricity and it is in Russia because I do not think $0.10 is cheap .

I would choose to have my equipment in front of me and be able to cashout anytime I want  rather than save few cents on electricity .

There is 0 reason to risk my money to save few cents even dollars .
