Looking at the picture, they are using really old bitcoin ASIC miners from 2017.
A profitability calculator I found says this Antminer S9 can get $948/year of income in exchange for $1,371 worth of electricity. That's a loss of $422/year.
Obviously it's not profitable to use anymore, unless you are literally stealing electricity like these guys.
