@karinxxl, thx for the enthusiastic support! This particular campaign is restricted to users with 10+ Hive followers. Maybe we can launch something with zero eligibility requirements, so that new users can instantly earn some HIVE.
For example, a "Sunset photo" with a smaller reward, say $3 (14 HIVE).
Waivio supports social login with Google and Facebook, so that new users can post and earn rewards without learning about keys, delegations and such.
