unfortunately, the HBD system is broken (no convert "HIVE to HBD" function for symmetry when HBD is above $1, HBD not stable compared to other stablecoins, debt ratio is too high) and HBD also increases HIVE debt and causing the yearly inflation of HIVE to grow substantially in a bear market.
I would vote for returning the funds to the DAO / DHF.
Broken beyond help, it needs a rewrite.
