I was wondering whether mining is now more about the fun of mining and keeping Bitcoin going or if there was any chance of profit involved for miners like myself.
I currently have some Bitcoin saved up, not too much but enough to buy an antminer s7.

My electricity costs appear quite high to other peoples. I have a day and night rate which differ

11.89p/kWh - Day (0.18 USD)
6.63p/kWh - Night (0.10 USD)

each run for 12 hours 8 - 20, 20 - 8. So I say on average about 0.14 USD/kWh.

I really enjoyed the fun of mining when I had a 4 x GFX card system set up. I loved it. But I am now wondering whether this is just going to lose me money. I don't mind a small profit as long as I get my ROI. But is that likely to happen?
