Doing some research on what used models I should be looking for..

Its all about power efficiency.. Divided the watts used by the hash rate..

There is a site that tracks miners that are actually being used and the power consumption.

So the SHA256 (bitcoin mining) devices that I should be looking to purchase in the used markets are the...

Bitmain Antminer S19 Pro
3250W / 110Th/s = 29.5
Profitability per day as of 5/6/2021 = $40.0

Bitmain Antminer S19j Pro
3050W / 100TH/s = 30.5
Profitability per day as of 5/6/2021 = $36.10

MicroBT Whatsminer M30S++
3472W / 112TH/s = 31
Profitability per day as of 5/6/2021 = $40.27

MicroBT Whatsminer M30S+
3400W / 100TH/s = 34
Profitability per day as of 5/6/2021 = $35.09

Bitmain Antminer T19
3150W / 84TH/s = 37.5
Profitability per day as of 5/6/2021 = $28.63

Canaan AvalonMiner 1246
3420W / 90TH/s = 38
Profitability per day as of 5/6/2021 = $30.55

MicroBT Whatsminer M30S
3268W / 86TH/s = 38
Profitability per day as of 5/6/2021 = $29.19

Bitmain Antminer S17 Pro
1975W / 50TH/s = 39.5
Profitability per day as of 5/6/2021 = $16.75

Bitmain Antminer S17+
2920W / 73TH/s = 40
Profitability per day as of 5/6/2021 = $24.36

So the next step is now to find used inventory and prices on the above devices..

Looking at that data above.. The MicroBT Whatsminer M30S++ is highest profitability and has close to the top efficiency... I wonder what price I can buy that model for????
