Even if you are mining and selling immediately each week / month you will make profit. Enough to make it worth it? Probably not. The added electric is $50-$60 a month. And immediately selling coins would be like $300 for the month. So $240 profit a month.

But you can do better things such as mining the most profitable coin and selling then trading right away. Make more gains.

Or mining a coin you are going to hold for a bit. BCI right now the coin. Been mining and holding.
