ofcourse you can , but your main aim should not be bitcoin mining .
With the bitcoin mining I am making 30-40$/ month without spent any money .
First I started mining of bitcoin at cryptopia ( which is a exchange  of altcoin with respect to bitcoin ) .
I made download of software for CPU miner from the github and and tried with my pc it was working but I usually not using my pc open more then 1-2 hours .
Then a idea comes in my mind ( that can be used by anyone ) .
I created worker for the mining and puted the softwares in the about 10 computer of my area in cyber cafe ( use task manager to open your software of cpuminer .bat file )
Now I am making money easily from the mining . Here all the software are free to use , So try at once
