I have used gear. I can sell you
Bitmain L3+
Whatsminer M10
are you based in the USA?
I'm located in NW ohio, I mean that gear is pretty old so your price is gonna need to be pretty spot on even though this electric is coming free from the govt i'm not really interested in making pennys per day per machine to just heat up this house tremendiously
well a L3+ earns about 1.25 dollar a day mining at viabtc. Merge mine of LTC and Doge, it burns around 750 watts an hour.
so 750 x 24 = 18 kwatts
4 of them burn 3000 kwatts an hour same as a s19 xp
and the xp does .07 x 140 = 9.80 or around 10 a day
so 5 a day vs 10 a day
4 L3+ on eBay are about 600 usd
https://www.ebay.com/itm/195701495289?maybe 550 . they earn 5 a day they use 120 volts so you can scatter them all over the house.
the 1/2 ing is coming but doge does not half so they will not drop that much in price for daily earnings
If you buy four from me for 400 you have payback in under 150 days.
now look at the s19 xp loud as fuck must have 220 volts and is 3500 to 4000 dollars if It continues to earn 10 a day 10 x 400 = 4000 for payback.
so rule them out.
an m10 set to high does 30th or 2.10 a day burns 2100 watts price of 250 means
250/2.10 = 120 day pay back.
must use 220 volts. it is loud.
Avalon has some new gear. let me find you a link.
https://shop.canaan.io/products/avalon-miner-a1246-85t-3420w?VariantsId=10013this is 85 th it is in Texas price is 680 around 100 to ship so say 800
this Earns 6 a day so 800/6 = 135 days loud as fuck must use 220 volts.
so top of the line up's are kind of stupid as it takes over 400 days for payback.
If I had your setup. I would do
10 Avalon for 800 each with 135 day pay back 34 to 35 kwatts
10 L3+ for 100 each with 100 day payback 7 to 8 kwatts
1 m10 for 250 each with a 120 day payback 2 kwatts
this has you burning 45 kwatts an hour
you earn
60 for Avalon
12 for L3+
2 for M10
74 a day with 16-20 kwatts left over.
in 4 -5 months all gear is paid off
you earned 74 x 150 = 11110 you paid
8000 Avalon
1000 L3+
250 M10
9250
this means 11110-9250 = 1900 pure profit
you can buy more gear. And be maxed out to 65k around oct 1 as house is cooler
so let me know if you want the 1 m10 and the 10 L3+
