In short: PWR is a token which you receive daily at a 8% rate on ur delegated Hive Power onto @empo.voter; hence, this is a delegation service.
I also recommend you to check the documentation: https://hive-power-ventures.gitbook.io/hive-power-ventures/
Whatever doubt, don't hesitate to tag me and ask :)
