I suggest you pay 10$-20$ bounty and get a full report from people who are mining already
asking public opinion on where in the world to set up your 2.000.000$ mining
is like asking which coin should I buy on an exchange chat
I definitely advocate your idea, if the author want to buy plenty miners and build well working mining farm then definitely should have make a particular research.The question is also where do you live, because in one country the the price of domestic electricity may has different prices?
You could also try to make the whole project more usefull and relate it with other due to give them some hot air or something like that.
