I found this post late. To add my two cents on both subjects.
The problem with Hive and building stake is it’s essentially money. If you want to buy tokens - must use Hive. Enter games or buy nfts - use Hive. There are very few opportunities to use HBD.
As for the DHF, I rather see one person, one vote instead of weighted voting.
True that we need more usecases for HBD, but these will come naturally with smart contracts.
I cant wait to use HIVE/HBD to take a backed loan in the future for example. This would be a great use case.
Regarding the 1 person 1 vote. This can't work here.
What could stop anyone to create an army of accounts? Nah. inviable. weighted HP is a must for gov.
