Considering the fact that you finally learnt how to tag #vyb accurately, I'm sure you will learn about vyb as well.😅

Vyb is a tribe token like POB, pimp, dreem, leo, and the rest of them.

If you have A vyb delegated or staked, it increases your vyb voting power. It is similar to the hp delegation you are familiar with, just that hp helps you reward hive on posts, vyb delegation helps you reward vyb on posts. (posts with #pob or #vyb tags)
