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.
Yes, the power usage is quite frightening.
Just an oddball thought, the number of minable BTC is finite isnt it, what happens after they've all been mined?
Where will be the incentive to keep processing block data?
