If you re-boot, you lose a lot of history and a Cryptopia listing which is extremely valuable. If anything, modify the current staking reward mechanism and reserve dev fund rewards over time equivalent to the lost pre-mine.
This sounds like the most logical course of action to take. Any recommendations on what changes should be made to rewards (considering circulating supply+current price) and/or procure funds for feature integration?
While the price is low and dropping, I think you'll find people more accepting and generous. Something along the lines of:
1) Increase the max supply cap by 20m to account for the lost pre-mine.
2) Fork to reserve a solid chunk of rewards for dev funding (think 25%) that tapers off over time and not to exceed 20m at the currently proposed end of staking rewards. A compromise that allows immediate development and stabilizes the lost development fund with less reward % but same $$$ as price recovers in the future.
3) A governance system in the road map.
