when you mine, you mine to hold your coins and take a gamble they will reach multiples of what the current price is. if youre mining to pay your electricity bill, dont bother
This is the only reasonable way to answer OPs question...
Unless you get the electricity for free or super cheap you wont be able to make a profit when paying too much for the electricity.
Now on the other hand, if you are mining and plan on keeping the ALT waiting for a multiplication that is a good way to go. But its still a gamble.
