Personal delegating rewards don't fluctuate depending on other people delegating, you're receiving 8% paid in PWR and that's it.

It's not like other projects like for example holozing where they have a fixed 200K daily pool of ZING for delegators. If more people delegate at the same time to empo.voter, more PWR is minted daily.

The thing which fluctuates is the APR on the pool.

Have a good Sunday!
