@citronick jesus 168 units? each pulling 1100 watts ? and you already have 108 S9s that is a huge farm comparative to most. I hear good thing about the A7 but its hard to pass up the efficiency of the s9 at close to 14TH for 1400 watts, I just hope these ones are not duds.
Yeah I hear you on the go big or go home but , I'm working with a much smaller bank roll and I like the ability to have direct access to my gear in the house and the garage for now at least. I only have access to around 130k or so watts of power so I have to go with more efficent gear
GPU's and the 14NM asics.
If some of my stashed coins strike big I will look into hosting a large amount of asics but for more I'll just Marvell
at you big time miners /respect
All the ASICs are eating watts at Cryptoboreas, Labrador-NFL-Canada - cheap hydropower.
My group pre-pay 3months in advance for our hosting+power bill - that gets us maximum VIP discounts.
We dont buy PSUs - rather we rent them from hosting provider - this way, they take care of all wear and tear, replacements etc.
I own only 30% of the farm, the rest are split between 3 more investors -- all retirees using their retirement funds LOL.
The wives werent to happy about this idea 2 years ago.... but now whole different story, we have ROIed and expanded on the proceeds.
2016-2017 was a good year for mining. We were lucky to have cheap Canadian hydro power and that was a major CSF in the mining investment.
I will bank on the A741s any day - they run very consistently and easy to manage.
I rather have stable environment with lower hash vs higher hash but needs babysitting all the time (this formula applies to GPU farms too).
Asics need to be install and forget as much as possible. A good night sleep is better than worrying all the time and excessive monitoring round the clock.
I have VPN and TV access to the farms at Cryptoboreas and GND (small farm of 35 x A741s).
I have access to the switched PDUs too for power cycles - so I can do my own thing in addition to onsite engineers.
My group's farm is by no means huuuge - but its not small either - there are bigger farms like what "blockmines" have which is x5 bigger.
