I still haven't signed up. My first thought was that I might not have the time or the patience to complete tasks too often, or validate tasks to see if the users really fulfilled the requirements. But I've been seeing more posts talking about Kryptonia lately, and I'm starting to think it might be an interesting way to promote things. Not only the upvotes and interactions from the users doing the tasks, but the upvotes from the bot sound like a nice incentive too. And yesterday I found out we can even buy SuperiorCoins for STEEM or SBD... I'm getting tempted to sign up and give it a try.
