I love the idea. The only flaw I can see is what would motivate a staff member to excel and strive for an incentive without a financial reward (other than bonuses) in place? I understand pride in the project and work would be the primary attribute you’d be looking for, and you want the person to take pride and be exceptionally motivated of their own accord - but I can’t see a ‘permanent’ salary with no hope of that increasing as a viable option - even if their own project and therefore tokens increases in value over time
