Yes, yes it does, as long as you are getting more than a 5% discount compared to buying with USD on internal market, it makes sense to buy Hive and repeat the process until you're all in on the collateral.
An alternative is to hedge your risk to Hive price over the 3.5 days by selling the HBD for fiat, with some strategy for buying back Hive during the 3.5 days.
thanks a bunch!
