HOW IS THIS GUY DOING 2 mh/s on zec??
dear god, I have some high end gpus, 6 of them doing nothing like that... like 480 sol/s each
Mining farm... rented hash... it isnt impossible.
I could shove ~34 Ksols into a full 48U rack with 4 PDUs of 30A 220V. That is 48 GPUs safely with power overhead in real 4U rackmount cases, no risers.
2000/34 = ~59 racks worth.
With risers, places like Bitworks are cramming 6-8 GPUs into a chassis, but those are lower power AMD cards, this is using 1080 TI FEs. You still have power limitations both ways.
Also, that miner may be running their own pool and using flypool as their target rather than host a node themselves... a few pools do this and maybe that is a private one using flypool.
