Thank you for helping, I'm grateful to be chatting with people actually doing mining
Have you found that you were able to remain profitable regardless of mining difficulty increases?
How long have you found your rigs remain profitable before they are surpassed by superior technology? 6mths? 12mths? More? Less?
Have you factored in labour time requirements for this or has this not been physically included in the expenses section of COGS?
Time between miner models is strictly set by what the semiconductor industry can provide. So far even more than 2 years after 16nm video cards started shipping at all they are *still* tweaking the 14/16nm nodes. Bitmain released the s9 (16nm) in early 2016. My crystal ball says miners will remain at 14/16nm for at least another year, probably more.
Labor? 25-30 miners does not take up much space, time involved is mostly unboxing and a few min to plug in/setup each one.
I just set up 3 avalon 741's and ordered 3 s-9's
we should be doing the next solar array and I want ready made gear to go on site.
we will be over 100th soon plus the gpus'
90+18+14+7 = 129th for btc
