I read it in an article, but that's beside the point.
Even if the costs are $0 and electricity is free, during halving your profits are still cut in half. That was my point.

I think it's a rough eastimation not a real cost. Maybe they calculated it based on the cheapest power some Chinese miners have
I've read many other estimates that gave a much higher cost of mining and came to a conclusion that everythiung below 5000 dollars would already put most miners out of business.
Profitable mining is depending on the cost of power somewhere between 5000 and 6000 dolllars. I guess at this moment with price at 4000 there's not a miner in the world that wouldn't be mining at a loss.
