I think it should either be linked to something more stable, like the dollar or gold, or else a % of the requested amount.
% of requested amount, actually, seems most flexible. And if successful, the fee can automatically be reimbursed with no need to add to the requested fee like now. I hate that we just burn dash up now anyway
The reimbursements could be above and beyond the set budget because the fee was burned in the first place, so we're not creating more just replacing the burned fee. I think that can be done without any security risks.
