Mining this days not profit as before, i think go to mining for most of us not good, may for who the electricity is very low in his country.
Mining is a profitable investment and it depends on electricity free country. So those are use solar panels for electricity it make good profit and majority of the peoples are concentrate the trading only so mining demand also increase upcoming days. Many new GPU mining rigs are enter into the market so old rigs are make low profit on current traffic.
If you're living on the tropical countries like USA, mining is somehow profitable because as you said that's dependent with the electricity costs. Since tropical places like Western countries, is not having expensive power generation, unlike most asian countries. If I was having enough capital to buy solar power generation equipments, I would invest on that just to cover the cost of mining electricity consumption; so I could do mining operation successfully without worrying for huge bill for electric charges. Profit gains would potentially gaining higher profit, once it stabilizes.
