I have been thinking about stake sizing recently. A minimum of 50 FOAM makes sense if the token trades for $0.05 - $0.10, but if the token decreases or increases greatly, it changes the incentive formula. Someone may wish to contribute to the map, but it can quickly become cost prohibitive and risky if too much is at stake. Perhaps the minimum staked should take gas costs into consideration. Gas costs both protect POIs from challenge and prohibit them from being created if they are substantial enough in relation to the minimum staking cost. If the price of FOAM increases, say, 100 fold, an incentive would emerge to nitpick challenge POIs or attack them for no reason because the reward is so great. If the price decreases by the same, there is no financial incentive to challenge bad points because the reward is of no consequence.
By what mechanism is the limit changed? If reduced, or increased, what happens to the existing POIs?
Has anyone else been considering this?
