Given HBD is still more than $1 now, it might make more sense to accumulate liquid Hive now, which can then be converted to an equal amount of HBD after the hardfork. Assuming that Hive price stays stable or increases during the time before the hardfork, this should yield more HBD than directly acquiring HBD right now (although this strategy might sacrifice some yield, those losses should be far more than compensated by the increase in HBD it should achieve). But that's just a theory, not investment advice :-)
