The idea of rewarding longer-term believers in a Defi project does seem to be at odds with the idea of creating a trustless system. However, it may be possible to balance the two objectives. For example, rewards could be structured in a way that incentivizes long-term holders without creating a situation where they are rewarded disproportionately compared to short-term holders. Additionally, rewards could be structured in a way that is more transparent and verifiable, so that users can be sure that they are being rewarded fairly. Ultimately, the goal should be to create a system that is both trustless and rewards long-term holders for their commitment to the project.
