Sorry. I thought you meant 25% fee on HIVE => HBD.
Got confused there. My bad.
This is much worse. It breaks the peg right away.

Yes but the 25% fee makes it less useful in that regard. It allows HBD to reach $1.25 without much resistance. Assume HIVE's market cap is $10 billion. The haircut rule won't print more than 3 billion HBD (considering the next hardfork). But HBD being $1.25 means 25% overprinting. $750 million more HIVE.
