Ever seen this one?
https://www.asicminervalue.com/ I think unless you have solar or score a deal on a cheap miner it would be best to look into a gekkoscience miner or a bitaxe supra or ultra.
USB miners are highly inefficient and mostly for learning purposes, im looking for ASICS of 2500W+ like S19s etc.
Thanks for the website
Your power cost is important.
Noise factor is important.
Durable miners are important.
I have 8 whatsminers
two m10s
two m30s
four m50s
seven of them are perfect and one has a dead board.
they are durable easy to control remotely. you can downclock them if it is hot.
the m10s are not efficient but cheap and durable. if you have very cheap power they are okay.
the m30s are more efficient but cost more if you have cheap power they are better.
the m50s are better but cost more if you have a bit more costly power they would be the choice.
m10s do 31th
m30s do 96th
m50s do 110th
what I like about these are the free remote software you can down load.
if you have any desk and the whatsminer software you can instantly control the gear from any pc in the world . i would recommend them if noise is not an issue .
if noise is an issue s19s using braiins with a down clock can help. as fan control works well if you down clock.
