What is the connection between the TKR token and the app?
As i know, one from connections is that TKR token holders will have dividend from profits earned by selling licences to CryptoInsight application.
Not exactly 'dividends', but airdrops as mentioned by wnj.
Right now no token utility has been implemented yet, this will be the aim after the update in Feb. The licenses you refer to is what we call subscriptions, that and other in-app revenue generating will go towards a pool that will be airdropped (largely).
