I am not confident on mining but most of my Crypto Enthusiasts friends are setting up their mining rigs and they do get passive income but I don't really think they are earning a lot than earning on trading or buying altcoins and wait for their pumps.
My friends aren't yet getting their real earnings through mining but I do earn more on buying cheap coins and selling them when I already get high enough profits..
For me I should choose buying coins than mining because I am indeed earning more than mining.
