Some quick Maths for fun, because we like #'s.
This current Hash whale is pumping ~400 Ph.
This would take about 3.750 S19 Machines.
Consuming about 12.418.500 watts.
@$0,10 USD for electric can generate about 13k USD profit/day, after the ~30k/day in electricity to run.
So they would need to smash a block every week to stay profitable.
Interesting I would say.
