A miner that schedules itself onto any GPU node is a workload like any other, and its economics come down to one subtraction. Drive the cost term to zero and the answer is always yes, which is the whole reason cryptojacking exists. A qualitative argument: the original never recorded the figures.

The honest reason the homelab exists. Port forwarding accumulates: one internet-reachable service per forward, several of them on hardware nobody will patch. A 5 USD virtual server does not make the listener disappear - it moves it somewhere you control.
