For me, my plans are to earn more and invest then open up a mining farm in my country.
From what country were you at right now? If mining is visible in your country then that would be a safe way to do so. However if you are a pioner in your country then you have to consider a lot of factors especially the climate if it is hotter then the electricity would be thin which also means that it is costly(not good for mining)
You are right, you need to take into account a lot of factors. And before you seriously engage in such a business - you need to make a cost estimate.
I plan to buy a new house and a car using my bitcoins
