hi
thank you for your comment. if i could hold my order what do you recommend ASIC for better ROI for same budget and with electricity rate is 0.08c per Kwh.
This shows you do not know much about mining which is okay everyone needs to learn.
I simply ask is it coming to you in under 10-20 days or is it a long wait?
If you get it in under 10-20 days you may as well go for it.
you could buy 6x s9 used units. at 600 each with a psu they are 3600 usd
they will do 78th and burn 7200 watts
78 x .35 = 27.30 see viabtc.com =
https://www.viabtc.com/7.2 x 24 = 173-175 kwatts a day x .08 = 14 usd
27.30 - 14 = 13.30 profit.
6 x 600 = 3600 for 6 s9's
3600/13.30 = 270 days to break even
they take up more room but are a tiny bit quieter .
would I buy the s9's for 3600 or the m31s for 8000.
I would more likely buy the s9's. but my power is 1/2 the coins. not 8 cents.
I rather lose 3600 worst case than lose 8000 worst case.
remember if your 8000 unit fails your hash rate = 0
if my units fail I drop from
78 to 65 1 unit dead.
78 to 52 2 units dead.
so on and so forth.
It is not an easy call what to do in your case.
