Was also trying to piece this together but using Medium of Exchange…

Maybe the ‘s’ is space. So, as the time during which BTC is being used as a MoE increases the space/geography over which it is accepted as a MoE also increases. Who knows? Fun to think about.
Yeah, that's more likely what MoE stands for. I checked Wikipedia for the mathematical uses of s, entropy is one, but thats capital S, small s is specific entropy, the entropy per volume/mass/etc. of something. And either way, I don't really see why entropy would belong in the function.
