Amazing price!
I wonder why we hear so little about big farms in your country. As I said before look into used miners. You would get much more hash power for the same price. Efficacity is irelevent with this rate.

Also, keep in mind that PayPal offer no protection if you send money as friend or family.

Not exactly what you are looking for, but I could be interested to host 20 Kw at 0.080$/Kwh. Over a few months, this rate should cover shipping to Canada.

So Avalon6, Antminer S7, Antminer S5+, and SP50 ?

This price is higher than eBay!

New S7 now goes for 2.4 BTC, more computing power and way better efficiency.

Any of you actually purchased Bitcoins these days as its price is quite low? With all these predictions of large increase, it would totally make sense to buy.
Predictions of people who buy new coins have more value to me.

By far the highest probability of anything electronic dying is when you turn it on - lots of extra stress on a lot of the components, especially inrush currents in power supplies.
This is the reason some companies tell their employees "leave the computer on", despite the cost of the extra electric usage.
So your suggestion is to underclock the miners during peak hours? Hard to tell what to do, at that price its lots of money to maybe increase life of miners. Is there an easy way to switch overclock/underclock on a timmer ? |

An other random guess  : 550$ That's the number I used for my predictions of ROI. |

Of course it would be worth it. Don't even have second thought on it since the difference of rate in peak hours it's crazy high as opposed to normal hours plus it's just 5 hours a day so it would even help lengthen the miners life as it gets some rest daily as opposed to running it 24/7 so the pros are more than it's cons so switch the S7 off during peak hours.
Cycling on and off daily actually shorten life of electronics. Thermal dilatation of chip compared to PCB bends the leads of the chips and eventually fatigue fails them. Good board design would not be affected by thermal cycling while bad ones would be destroyed. That being said, I don’t think this would really affect the reliability of your miners and I would most likely shut them down every day at that extreme electricity rate. I have had a few miners die during the power-up phase. That was from a cold start. That's why I suggest that he leave them in an idle state where they're only drawing like 50W to run the fans and keep the OS active and plug the cable back in when the cheap rates go online. Is that due to cycling? The power difference between 50W or 0W and 1200W is very big. 50W cannot keep your PCB warm. I was about to write the same thing. Mastsetad, you've been faster |

Have you thought about 2 phases immersion cooling?
After days of research and planning I’ve concluded that in my area it's not a viable option for cooling (money wise).
In yours, it may make sense. Plus it's super cool to use!

Have you thought about cloud mining? Plenty of people choose to do so. I personally prefer to have the miners at home since my electricity is cheap and 5 months per year I use the heat to warm my house.
For my first 4 miners, counting heat recuperation I have electricity for about 0.06 $US/Kwh
Where are you from ? u have a cheap electricity you so lucky  I'm from Canada, Quebec. We have hydro power and good rates to $US. That is why electricity here is cheap. There is also a plan that I might subscribe to. I need to do the maths but on that plan there are two rates. One when outside temperature is above -12°C and another when it's below -12°C. Rates are 0.033 $US/Kwh for around 11 months and 0.18 $US/Kwh for the coldest month. You obviously shut down your miners when you switch rates. I'll do some researches on the numbers of hours per year forecasted on each plan and see if it makes sense. Switching plan would also imply heating my house from another source than electricity (oil, wood or gas). Cost of heating source conversion would also have to be included in my calculations. |

You have a few options for cooling.
If I recall, Morocco tends to be dry - in which case "evaporative cooling" is DEFINITELY an option to investigate.
Mechanical cooling (aka Air Conditioning) will cost you appx. 20-25% (depends on the efficiency of the A/C unit) of the amount of electricity you use for your miners.
Fan cooling via massive airflow doesn't work so well in hot (high 20s C and higher) temperatures, if that's your only option PLAN to underclock (and if possible undervolt) the units to be ABLE to keep them cool enough to operate.
Given all of the factors above, I doubt you will be able to profit enough with an S7 to be able to pay back the cost of buying one, even if Bitcoin price takes a BIG runup around the halfing this summer.
You are lucky to have evaporation cooling as an option. I would research it and go with it, cheapest option there is really. I live in a area that weather does not allow evaporation cooling so I used lots of CFM's from fan's and a good exhaust. I think your country's heat might make this a little bit hard though. AC you will not be able to justify it's just to high at this point in miniing. in morocco the heat is normal, i'm gonna use "evaporation collin system i watch some vids it's simple , why you can't use evaporation u live in desert or what ? Evaporative cooling works great where you can easily evaporate water. In essence, you mostly need dry ambient air. Desert would be quite good to evaporate water, aside its average high temperature. Best places are where there is dry air and moderate temperature. |

With Hashnest you pay quite high maintenance (electricity) fees. I am still looking for ways to prove I'm legit. Maybe for a start, it could be in person delivery of hardware. Less scary than sending your box by mail. Let me know abdeljabbar if you want to come by and see Montreal’s snow |

Cloud mining is full of so many scam sites it's scary. If you do choose cloud go over to hashnest, that is about as good as it gets. But I like to have mine myself as I like to tinker with the miners. There is initial setup costs with a mining area but if you are planning to mine long term it is not a bad investment. Keep in mind there is no ROI guarantees. I would also guess that many people were scammed on cloud mining. Given my electricity rates and my capacity to reuse heat I would have liked to host miners but it seems impossible until I get that many posts which grants me a better title in this forum. Meanwhile, I will keep reinvesting mining income on new miners. |

Hello,
i`m waiting for my order of 3 antminer S7 (14.19 TH/s Total) with 3 PSU expected to be delivered this week and the Electricity Rate in my country is 0.0066$.
i want your help about what to do next ?
- Pool mining OR Self mining ?
- if its Pool mining what pool should i go with ? and what is the best Pay out method ?
and i`ll appreciates any advice from you guys:)
thanks
Are you sure about the number of "0" in your electricity rate ? If it's acurate you should definetly look into buying used miners instead of paying for such efficient miners as S7. |

I pay my electricity in $CAD and all pricing here are in $US. Have you seen floating electricity prices? (Based on US to CAD exchange rate)
I could lower my price but, I want to make a fair profit out of doing it.

You know a good place to buy these things that accept Bitcoin ?
Newark has good price for all little components
