Hey guys, a bit of an semi off topic question, but i'm mining with 2 S7's. My electricity is almost free.
Since the last diff increase and seeing the BTC profits halve every 3 months i'm actually thinking of quitting mining.
As getting a S9 doesn't seem to be a great ROI either.

Just selling the miners and hodling that in BTC seems to be more profitable in the long run than keeping them on.
Anybody else feels the same? Or am i just having a bit of fud?.
