I'm not sure how much is there at present and if it would make too much difference - 5/6m SP worth of VESTS is required.
There is a decent list of 50k+ account holders who aren't voting at all, or who could switch existing votes to the witnesses currently at 21/50 - I think we just need to wake a few people up!
It would be about 12,500 SP per day. Maybe the proposal could even be a call for decentralization and it goes to active Witness voters or something to spread it out so any one person wouldn’t get that much. I also think we need to weaponize the reward pool. Time for battle.
