0.17 BTC / day using what hardware? or did you buy hashing power and thats it?
so if its not profitable why all these guys have those mining rigs? xD
Never "buy" hashpower,it's a losing proposition

2 Gridseed 5.2mh blades,8 Gridseed 360mh little miners & 7970 vid card @ 575mh=14450 mh.Got 5 1.3mh fury's coming,so 14450+6.5= 20+mh

I didn't say BTC mining is not profitable now,it soon will be,unless your power is .06 cents per kwh or less & BTC hits that almighty $1000-1500 mark...............

I'm paying my electric bill with earnings from my miners,my job doesn't pay well enough to supplement that
Or as crashoveride54902 says,mine & hold & hope for a massive rise in BTC price

& your correct on the megahuge mining farms,crashoveride54902

They will be in control very soon,not sure how that is going work in BTCland..........
