Due to the downfall in the market it is impossible to Earn from mining as the electricity consumption is more than normal also the bill is higher than the profit which comes from mining. Apart from that you need to invest a lot of money for buying cords and other stuffs which is very complicated.
You got free electricity (or extremely cheap) in some countries. So it is still viable. Once the profit is gone you can always mine coins you suspect might rise in price in the future, so it won't be profitable at the moment, but can be in the future. That is what I did more than a few times when my graphics card wasn't good enough anymore, made money even from that mining where I was losing money on a monthly basis.
