P.S. I do not recommend newbie to jump into mining. This is game for big investors.
I disagree. I think newbies should definitely try mining but start small with 1 Antminer.
I can see your point, but you could put it in a garage and not worry about it.
I would love to disagree with myself as well (I'm also supporter of: more miners = better decentralization = safer network).
But I have seen so many newbies invested in this and then being surprised "how come my miner is making half of what did few weeks ago" etc.
My point was: do some investigation first. Calculate possible profits, estimate ROI time, evaluate risks ... and based on this decide whether it's worth it (rather than just jump in)
I agree with that. New people definitely need to do research. When I started, I had no experience but I did do plenty of research. I misunderstood your original question.
