Someone must have already figured this out. I'd like to know at what electricity price Gridcoin breaks even, assuming roughly average returns. I know this is a function of GRC's price, say, in dollars, and the number of users. I was idly speculating about the possibility of covering electricity costs in places with cheap electricity like Iceland. Theoretically, distributed computing projects could earn useful foreign exchange.
Of course, this could just be another one of my bad ideas.
