glad you liked it :)
if you have a powerful machine, mining would be good choice , otherwise It would not be profitable
anyway if you want to start mining there is a great post about it which is using Ubuntu server 16.04(I tried it and it works)

Hi there, are you into gpu mining?

I am interested into mining in fact I decided to buy a miner in a month or two but I now have doubts because lots of people are giving negative feedbacks about mining.

If you have experience in mining, can you give advice on which is profitable, mining bitcoin or other coins, and what coin is it? Buying mining machine or GPU is much better?

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

Which is profitable mining with S9 or PC with 4 x980 gpu? I dont have problem with electricity take it out as a negative factor. What do you think is more profitable?

if you want to go with bitcoinn S9 is the answer(I never used a miner, though), try to read this link, it gives you a lot of information

GPU mining even with that setup wouldn't give you that much hash rate.
