What if you consider those that will share hive with at least one person daily and provide evidences.

Also, you can give tasks to people, tasks like, do a video and tell us 1,2 or 3 things you like about hive.

Another awesome idea is, you can give taks like, creating proportional materials (graphics, banners and art for hive).

Again, music for hive can be rewarded.

I'll think of more and share.
