Having a bunch doesn't improve anything. efficacy is same for one machine - as it is for this bunch. Fact is, he is barely breaking even same as everyone else. Only the guys stealing electricity will prevail.
Oh so true! With a network hash rate of currently 216.6 PH/s and next difficulty in the area of 31.5B we can see where this is going. As said before I'm really impressed by Spondoolies-Tech and their products, unfortunately not even at 0.55 W/GH (off the wall) it's possible to reach a positive ROI any more if not having free energy (and again and again, THERE IS NO FREE ENERGY, period!).
We need the new tech, more TH at less W and lower price! It's all going to hell too fast, I'm really wondering how large mining farm are going to make a profit considering all costs involved with decreasing mining reward and current low FIAT exchange rates.
without mining bitcoin is a boring exercise, like investing in stocks or mutual funds. It will be not a very interesting proposition. I think that, if btc price does not improve, many people will be out of mining by Jan, Feb. Cloud mining is a joke that is designed to take money from people who cannot count, so it is not a path forward.
Edit: as soon as I posted this-news re
SP-20 (Jackson, 1.7Th ) appeared on cryptocoinnews (ZeroBlock). Not here yet, Guy/Gadi.
1100 W, so i can repurpose my evga, 4PCIe connectors, just 60dB. Price has to be right, though.
