The incentive to use the DHF "correctly" should be to fund projects that drive the improvement of HIVE as a whole which would benefit each and every account holding HIVE, yet we're using it "wrong".
Could there be a problem of misaligned incentives in the design of the DHF?
Are there not enough dolphin and orca accounts involved in voting for DHF proposals?
The problem is people, not technology.
Probably, but that's really not the problem.
