The Holozing tribe is supplementing Inktober with additional rewards. I think they want monochrome images suitable for their game. You might look up their requirements.
I acquired 77,000 CCC just for #inktober . If you add the tag #creativecoin to your drawings; I will upvote the posts.
I don't have any HIVE; So, I am only upvoting #creativecoin posts.
Good luck.
