Or $68/transaction supposedly if electricity cost at 11 cents per KwH is used. Actual transaction fees run around $0.20 for on-chain which implies either math is wrong or per block reward is sufficient still (total blocks I believe are fixed with increasing difficulty). Does this analysis take into account secondary network transactions? For example wire transfers are relatively expensive to process still, but are often used to settle huge volumes of things like ACH payments, nightly sweeps etc.
