Yeah, for a split second the idea of a stable coin that increases in value by a set amount over a set period of time is a little weird...but actually, normal currencies do the opposite, supposedly to encourage growth of the economy. Every year the dollar drops in value by 2% about I think. America loves it's hidden taxes.

It's just code and math. I don't see why you couldn't do it. Though I wouldn't suggest stabilizing it to USD. One smart thing Libra chose to do, they stabilized it to multiple currencies, so it's actually gonna be more stable than any of them, if they do it right. I would think maybe you could peg it to the price of other goods...but exactly what you'd probably have to do a study on.

Maybe a combination of multiple precious metals? But that might be effected by the eventual asteroid mining. Crops might be too unstable. Maybe if you combined a bunch... Not sure if there's any way for something to be truly stable though.
