HBD in circular economies is definitely a primary use case.
Investors staking HIVE is another use case. The power down protocol ensures against massive dumps.
However, investors staking HIVE actively lose part of their investment if they don’t either actively curate or use voting bots or a delegation pool.
HBD Bonds are more suited to the average investor. Especially those looking more for fixed returns rather than speculative returns. And, HBD Bonds fix the problem that 20% APY with no lock-up period puts the platform at potential risk of massive dumps.
