I am a large FIM holder (from IPO) and I even I think it would be nice to have incentives for smaller FIM holders to get involved.
We'll think this through how to arrange it, but it's very difficult to do without skewing the incentives towards unfairness.
Bonus rewards are not paid very often, so random variance will play a big role and even small time forgers have a considerable chance of hitting the bonanza on one of them.
