Mining is now thoroughly dominated by large, commercial facility. They were very profitable before the halvening, and they are still profitable. Any struggling small scale operations that are now unprofitable are too small to notice if they shut down. Also, for at least a few months, unprofitable miners will keep going in hopes that the exchange rate will go up and save them. Some will argue The price of bitcoin has been $250 for almost a year in 2015 so expressed in fiat mining was 2.5 times more profitable (yesterday). So now it's 1.25 times more profitable. I disagree. These fairly minded people forget about the difficulty at about six times what it was in 2015 ! Hashing will drop, it must or Bitcoin price must double
