I do not consider mining profitable, as you need to have a fairly large amount to buy equipment, have a room where you will mine, and you need to pay large electricity bills. Do you need?
It takes capital to start mining if the electricity becomes an obstacle to get big profits. I think mining will be a big profit when the price of the coin is expensive in the market if the price is down then the profit that it can only be in use pay electricity. before you start to mine better you think first right.
