You're kind of missing the point, the miners are driving up the energy waste, your little Pi is useless in bitcoin mining,
however that little pi could run a PoS network.

Everyone know you G.Maxwell pet cat, shoo bad kitty.

For the record, I was calling the now non-entity formerly know as Lauda the pet cat of G.Maxwell as she did his bidding on multiple occasions.
