Mining needs too much investment as well as stash and hardware in order to have a start up in this lean field. It would cost no less than 2500 - 10k USD to buy all the equipment you need to begin with mining during current days. Investing in Bitcoins will also be very expensive but it gives much better returns as well as possess less risks compared to mining where your electricity could cost higher or even cut off which will lessen the efficiency of your mining equipment.
