Smart idea, but I was more thinking about daily use and maybe fiat to fiat exchanges.
In Australia, they have the AUD in Europe the euro. I think if shops would accept a hive currency, they would like to have an asset.
Some people prefer other currency more as USD.
The idea of an increase in peg is cool. But I think I need some days to think about and maybe bad points of it :D
Edit: maybe it can be some value pool that can generate other currency and back. That would add all liquidity to that pool and would be super flexible.
