It feels like wasted power. You could at least be earning something off it. The creator can either take a cut if it’s free or lump sum for paid.
I’ve seen a few idle games take up a lot CPU resources, not necessarily GPU so it had me wondering. Why not make it mine?
I assume you mean for the computer owner, not the game developer? Assuming it goes to the owner of the hardware, not really that useful. CPU mining is incredibly slow and GPU mining would not even necessarily break even on electricity costs. If someone wants to mine, they should just run a dedicated mining program. Wasting electricity to do pointless calculations for tokens is an outdated idea anyway.
