I am taking a wild guess here, by saying that a more realistic global average would be more like $2000 per coin.
I think that's pretty much on the lower side, but I have no doubt about larger miners to have way lower generation cost ratios than current price levels.
If you take into consideration that larger miners have much higher block generation frequencies, the cost per minted Bitcoin decreases significantly, even if your electricity rates aren't the cheapest in the industry. In that regard, you can counter electricity rates by having yourself account for a large part of the network, but in Bitcoin's case, it will cost you dozens of millions in gear to obtain that sort of advantage over the rest.
So, it is still very profitable for a lot of people to continue mining in a lot of countries.
I'm not sure if that's actually the case. Current levels are really pushing home miners to their limits, and it may even have resulted in people to swallow current unprofitability in the hope that the coins they generate increase in value in the next couple of months. What if the price remains below $7000 for the rest of the year? People's patience doesn't last endlessly unless they are hardcore Bitcoin enthusiasts.
