those farms can sustain the halving, so with the same bills cost you would also
The only thing is we have no idea what difficulty and value will be around having. We have had a decent jump from 230 or so for longest time to current 450. So we are experiencing a jump up in value.
One thing I need to know is value at having. It is true these mega farms have every single advantage. But I hope home miners with decent electricity can keep mining, I will do it until it's not feasible.
For the mega farm to have every advantage they need to have a way to use the heat.
Many big farms have an issue with heat they treat it as a waste product.
with a thermoelectric device, you can convert at least one portion of your heat in power again, this way they should another plus on their already cheaper electricity
