Daily miner revenue divided by TH/s for the Ethereum network. This metric trends down over time, but shifts from trendline indicate more / less profitable periods for miners (due to increasing prices, transaction fees, or favorable difficulty adjustments). Chart uses 7-day moving average.
Note: on 15 September 2022, Ethereum changed their consensus model from Proof-of-Work to Proof-of-Stake and this metric became obsolete.
