Unless you already have the mining gear laying around - it won't be profitable. Even if you have the gear laying around it still likely won't be profitable. I have quite a bit of gear, but cooling it in a Texas summer, even with solar picking up a chunk of the energy, it's just still not worth it.
if you wanted an idea of revenue vs profit depending on your gpu and what coin you'd try and mine. whattomine.com would show you all possible scenarios based on your electric rate and the hardware you have current difficulties and current exchange rates of various cryptos.
I've dabbled in gpu mining for years, the golden era were the times I could pull in $50 a day while electricity only cost me $5/day, hardware paid for itself in a few months vs the years it takes now. It's a fun tinker type hobby at this point, and I'd only dabble in it currently with the mentality of a prospector. aka mining XYZ I think is interesting and its value possibly skyrocketing later (nobody knows) Winter time is more interesting/exciting because at least the waste product is useful (free heat) off all the rigs keeping the house toasty.
