Thanks for all the comments guys we have been mining on a small scale for 6 months with 100,000 gh/s just trying to see if we are missing something on going larger.. all comments are very helpful. Joeyface

Bitmain Yoshi Gopo is selling a 1 Peta which is 500 S4 for 420,000 which = 850 per unit.
Cost to run them at the same location is 80kw per month. to find out how much kw per month you will
be using in a setup like this simple 690,000 of constant watts used http://www.rapidtables.com/calc/electric/watt-to-kwh-calculator.htm
Energy in kilowatts hour 16560 x .11 = 54,648 a month -/+.. 1 Peta is bringing in around
3800 - 4100 in coin in a 24 hour period. Cost to run mine at Yoshi location is 1821 a day..

Gives a net return of around 2100 - 2300 a day.. 70k+ a month  880+ a Year ... Total fees includes power to Yoshi are 54- 56 k per month

I guess maybe your right must be something i'm missing 80kw per month is 56k... based on today's price is 877k   profit  iam looking 2 see if these people are real maybe i'm missing the big picture...

I have been in talks with Yoshi from bitmain about the buying of the 1 peta farm they have.. They have 2 peta for sale is there any one on this board that has done business with him thanks . Joeyface

Hey guys thanks for the comments the reason i'm asking about other miners that might work better for this setup because maybe its something we have missed has a team.. We have only ever run S3 - S4 miners power cost is at 12 cents kWh which we have worked out with the power company. We made them a offer based on volume of usage. I have been told by the company ..Jan is when they plan to make it known on S5 specs and launch date is right behind that. WIll be rolled out in 3 Stages 300 Units Drops per stage.Should be totally online in 2 months after the first 300 go online.

Building a 900,000 Gh/s farm with all s4's going to keep rolling with the s5's when they roll in Jan 15.. have 15kv power coming in... using BTC guild pool have been for a while on a smaller scale.. 40 tons of AC... my question is what other miners would you guys use on this scale thanks again Joeyface.
