You can mine.
Depends... Where you live, power cost, cooling cost (if any), equipment costs.
I doubt if mining would be profitable unless the electricity costs are low, climate is cool, and you can bear the noise

But as he said that wants to earn a Bitcoin in two months, mining won't be helpful. Mining would give you roi in a year or more .
Instead, trading currencies would give you better returns.
But if you don't want to waste your time daily, mining would pay you in long run and won't require much skill.
