Well, if you really want to tackle this topic then I will leave you an additional idea to keep you thinking:
Give users the opportunity to schedule their rewards claim. Establish a collection period: weekly, daily, monthly ...
In case the user decides to use long periods, an interest rate could be applied, which could motivate the users to leave their rewards in the rewards pool so that they are redirected.
These sheltered tokens would serve as a passive investment and perhaps a dynamic ninja stake could be created for blockchain development.
Think about this.
