I've wondered how the Hive Blockchain gets to generate Hive and HBD and I just couldn't place it but now I have a little insight even though I'm still confused. But then I do understand that having both HBD buyers or Hive buyers is both advisable because like the example you made, at some point one is surely more important to an individual than the other just like on days when we have our HPUD Hive is more valued than HBD to those who which to participate in powering up.
Things are surely going to get better but of course all hands need to be on deck for that to be possible.
