CPI may make a better target for a better long term stable coin, but even if the [stablecoin] dollar becomes unstable due to inflation, basing it on something based on the US currency unit may still be better. I think the mindshare of the dollar is a bigger value than the relative stability of it. An arbitrary CPI will have zero mindshare vs. the dollar's very large mindshare.

If the dollar really shits itself, that mindshare will decline, and eventually down that road some other basis would be found. If that basis is a commonly accepted and used CPI, great. I don't see using something that is not commonly used as a value-add however. Hive should follow the market when it comes to a commonly used and understood abstract of value.
