Do you pay electricity bills ?
Yes. I have access to "relatively" cheap power.
Did you build your rig only for mining ?
Yes.
What was the investments for it ?
1190 euros.
6-7$ a day, it will take time before you get your ROI (if it's possible)
At least 6 - 8 months. I guess it's an experiment.
For a short while NiceHash gave 11+ euro per day as an average. We'll see.
I have hope that BTC will rise in value during the next 6 months or so.
