How are the tokens used? And can I buy them from within the app using a debit card?
Hopefully we can get some more help in this thread soon. You guys have been doing a great job answering questions!
You won't be able to buy using CC, at least not in the near future.
The KUE token is used for creating and voting for challenges. You can also delegate them to other users and split the KP reward from the challenges they create/vote for.
The KP token is used for buying stuff from the future marketplace, in-app purchases, offline partners.
