if we increase haircut ratio im out btw. That would be too easy to game to print an infinite amount of hive.
If we want a stable HBD, simple add onchain mechanic worth 1$.
Wallet creation. Pay hive or HBD. HBD is cheaper than 1$. So you get a discount.
It would be an indirect peg even after haircut in place. With more mechanics like that, perfect.
Another thing could be an onchain pool that allows high liquidy trades, that has a micro burn fee. Like 0,1%. With high volume, it would decrease the HBD too and would allow to reward liquidity providers.
