Yes a lot of people that do Tasks on Kryptonia are from Steemit as you will see from the large number of Steemit Tasks asking for comments/upvotes on peoples steemit posts.
When you signup for Kryptonia your first Task is free so you can check for yourself.
Thanks for stopping by Colin! That is what I am implying. You get a boost as well as earning crypto on a second platform for helping out others.
