Not maybe, definitely. A first-gen pi can mine at 200KH/s [1], and a 3rd gen pi is roughly 10x faster in cpu tests [2]. At 2 MH/s per pi, times 7 billion peopl

Not maybe, definitely. A first-gen pi can mine at 200KH/s [1], and a 3rd gen pi is roughly 10x faster in cpu tests [2]. At 2 MH/s per pi, times 7 billion people, you get a paltry 14 petahashes/s. That's a hair over 0.2% of the network... You'd need three trillion raspberry pis to get half the network. Good luck with that!
