mining bitcoin is not profitable these days unless you have very powerful equipment which will cost you a fortune for sure, these days XMR mining is more profitable than other coins and its price is increasing rapidly.
I did my mining back in the days but It was never profitable for me(maybe I was doing it wrong). if you want to do this it is better to go with mining machines , otherwise the electricity and other expenses would make it an even business or with a very low profit .
I hope you get your answer, this is all I have about mining
