You can not mine a shit using your CPU Because you are not going to be able to earn not even $0.01 a month of each coin that you want to mine using yours.
You have to buy a good gpu, and a few of them if you really want to have a serious income.
If you want to make a living based on those gpu's and bitcoin mining, then you will have to invest thousands of dollars to buy dozens of this gpu's, that needs to be the new generation of those.
But if your electricity taxes are expensive, then better to do not invest in this because you are going to lose a lot of money.
