I have 8 great working bitmain S3 units. I would include three 750w corsair units and one 1000w corsair unit. Also I have a dlink Ethernet switch, and two back up battery supplies. Located in STL would like to sell local but would do shipping but you pay shipping. I won't sell using paypal, I've had too many issues with them and eBay lately with scammers. Any questions just ask!
Will be adding another 1600 or so gh/s tonight, should be putting me at 4 th/s or so.
I sat on the phone for 30 minutes one day trying to explain to this other miner how PPLNS system works and i still never think he understood it.
Anyways, the pool is working great for me I think it made me about .65 BTC +/- in two weeks of running 2.3 TH/s. The payout is way better than any of the other larger pools I tried using.
