Probably not at the current difficulty. We'll likely see a difficulty drop as people turn their mining hardware off, though. – Nick ODell – 2016-05-30T17:44:23.027

If the fastest Bitcoin ASIC miner isn't profitable after halving, then the most miners have to turn their machines off right? The difficulty drop will be huge then. Will this lead to a centralization of new more efficient ASIC running by a few companies? – alexander – 2016-05-30T18:41:18.330

2Whether a miner is profitable depends in large part on how much the operator pays for electricity. – Nate Eldredge – 2016-05-31T14:54:13.373

1) We don't know your business model. What's your power price? Will you be selling the miners after a period of months? 2) Be careful in assuming that the difficulty will drop. The efficiency of miners historically has increased more quickly than the reward drops. There may be a localized stall or decline in difficulty, but as far as profit calcs go, I would never assume the difficulty will drop over anything resembling the long term. – brandondoge – 2016-05-31T17:19:39.427

I've downvoted this question because it has an obvious answer that's useless (which is "of course, otherwise nobody would be mining anymore") and a non-obvious answer that is individual to the respective circumstances. I therefore don't find the question useful. – Murch – 2016-08-11T06:55:27.530
