Mining isn't my thing but judging by the stack of S3+ and S4 units that a friend has asked me to sell for him I assumed that the S5 was not too far off...

Most likely your mate wants to sell because profit is not worth the noises after cost of electricity at current BTC price. I'm using my S1s, S3s and S4 as space heaters and make little profit. My flat is so hot that I have to keep my windows open.

Either your electric cost per kwh is high or your pool is not paying enough because I am making profit using S3's and S4's. $.12 a kwh electric and Slush pool. Winning combination.

Power prices are about $0.24 KWh in London for a standard domestic electricity tariff but my friend uses a power broker to negotiate much lower rates than that because his farm is in his industrial printing plant and his farm uses a small percentage of his overall consumption.

As to why he is backing out of mining I'm not sure but I suspect he doesn't have the time to dedicate to mining to justify the slimmer profit margins. I'll try to have a proper discussion with him about it before he pulls the plug . He's a canny businessman so I'm sure his reasons are sound and personal to his own circumstances.

I'm not sure on numbers but I think he has a lot of hardware. I remember him saying something about 30 S4s at some point. When he finds out how much I'll charge him in commission to sell them maybe he'll change his mind Wink

Thats rubbish pricing, I have $0.13 in standard residential in the UK.

I know.

These are the most recent figures I can find for London (base tariff)

British Gas: 15.1 pence per kWh
EDF Energy: 16.0 pence per kWh
nPower: 16.2 pence per kWh
E.ON Energy: 14.8 pence per kWh (2012 increase not included)
ScottishPower: 16.8 pence per kWh
SSE: 15.5 pence per kWh
