If I were to mine again, I would choose a smaller coin that is less popular. If you were to mine a lesser known coin, you could probably earn 2 to 4 coins per day and then sell those to buy bitcoin if you must have that particular coin. I am sure you could make many more dollars worth per day in that way.

It is crazy to mine bitcoin when so many others are available to mine. Example: When Etherium first came out, I mined it with only two video cards and earned 45 ETH in a month. The price was not good so I quit before I had the chance to burn any wiring. My point is that new coins are much more profitable. Less miners to divide rewards with.
