You are on point there - No one's got to it yet is the best explanation: YC?!? It's happening at the Utility scale with commercial miners, esp. with merchant (uncontracted) energy. Small producers (residential , commercial solar) just need an easy button solution without having to learn the crypto details. I don't know what that threshold kWh price is, but demistify that and one can define target markets across the US in one broad stroke with EIA utility pricing data. The formula in a prepackaged product with an app seems to be the only trick. Then get it in the hands of residential installers and boom. It'd probably sell like (can I say it on HN) liquid crack.
