RE: Usecases for POB is a must but first step - Ad revenue .

I think only rewarding the top user of something is not such a good idea. It is super hard to achieve and also it is somewhat unfair: i.e., the person with the most stake can easily always be first in that position (most PoB staked). So perhaps it would be better to spread it to more users rather than only to 1 person.

I like the second idea more, this would create a bridge to the fiat world which is so important. Also, this could be expanded upon!
