If we are going purely by the expectations pre-launch, it’s also relevant that right now the staking rewards are 200% of what was suggested in the original launch plan, so the staking parameter updates we are discussing don’t violate the Genesis expectations that you’re talking about, because they’re still well above the originally planned levels.
Plans can adapt as conditions evolve. I’m not trying to suggest any specific plan, just to point out that TRIBE holders can always change the plan if a better plan is found.
Many other protocols (aave, curve, yearn, …) use their rewards to incentivize different behaviors that benefit their ecosystems. Their gov token holders vote for this to happen, even if this causes some form of dilution, because they expect that these incentivized behaviors will develop their ecosystem like watering a plant. Incentivized behaviors have been a major factor in allowing these protocols becoming the dominant players in defi.
The $90 million dollar question here is, what is the best way to distribute the remaining $90m in staking rewards? It might be the current system, it might not be. The TRIBE will decide!
