In the same way that the high priests of Keynesian economics aim for a 2% inflation rate Is there a deflation rate that is optimal? (Assuming 2% inflation is actually optimal, which I would strongly argue it might not be… forgive me not a great question! 😂)
Probably also 0% 😄 But coins will get lost, I think we can’t do anything about this? 🤷♂️ If by deflation you mean price movements, then I‘d say we could look at the PC/chip market. Don’t know if we would call it optimal, but it’s a working market, still. Even if prices drop ~50% every year or two, or computing power doubles every year or two for roughly the same price.
