Overall printing HBD should be considered as an act of balance from the witnesses.... with the main thing to consider the Hive debt.
At the moment HBD is in a great position with around 2% debt. Hive has been conservative in this regards for a long time. With the increase of the haircut limit in the next HF there will be even more safe room.
At some point if we get above 20% debt, probably will be a good time to reconsider the hbd apr.
