We can monitor the situation and profit on it the next time around. HBD printing only gets out of control when the price of HBD spikes high and doesn't come back to $1 for a long time.

Printing the HBD isn't the problem... the problem is that HBD doesn't get burned when the price starts going down. It's a good thing all Dev funds are printed in HBD because this puts downward pressure on the price.
