Implementing a reward system based on watchtime using channel points could be a great idea to incentivize viewers to spend more time on your channel so that they can get the channel point rewards a bit faster.

Let me elaborate:

Watchtime-based Reward Tiers:

Create a reward system where viewers earn channel points based on their total watchtime of the streamer. For example:

1 hour watched in total = 50 channel points
5 hours watched it total = 250 channel points
10 hours watched in total = 500 channel points
25 hours watched in total = 1,500 channel points
50 hours watched in total = 3,500 channel points
100 hours watched in total = 5,000 channel points

etc.

As viewers accumulate watch hours, they receive channel points at each milestone. This incremental approach gives viewers a sense of progression and achievement as they work towards higher rewards.
