Just look the profitability history for the whole year of 2017 and you will get a quite good picture what it will be at what price and difficulty. So it varies A LOT.

Next difficulty check will be after 7 days and we are expecting about +15% rise in it because the current block times are somewhere at 8 min 30s.

The current mining profits are about $11 and have been lately in heavy bear sentiment.

So the near future does not look good for the quick bucks at this moment. Those who got these units on $1415 (november 2017 batch, in mining from the beginning of 2018) are in much better position.

But as you can see from the profitability history you have to look these things in much longer term than just 1 or 2 months -> annually
