An investor who can vote to release tokens from the DHF on their own, for the purpose of damaging the price, would be almost twice as large a stakeholder as blocktrades and that assumes that no other stakeholders saw the attack and would add votes to return, clearly false. For example, if blocktrades voted for return, the return vote would be 80 million, not 50 million. This attack is simply implausible to even happen, and it also makes no logical sense that someone with 50-80 million HP would want to send the price to zero.

Further someone with a stake only slightly higher than 80M could vote in all of their own witnesses.
