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
