You definitely are an edge case if you were already paying your utility bills in cryptocurrency. Otherwise, you spent fiat currency to bootstrap your use of Etherium.
I didn't mean that I pay my electricity bill in crypto. I meant that my small apartment has a fixed electricity rate so that I don't have to pay any extra for running 2 GPUs, and that I already owned the hardware to mine, independent of crypto. So I didn't invest anything. Sorry for being unclear.
