I'm a kik user but I don't think kin won't be the most used cryptocurrency. Most of the users aren't interested to buy and sell thinks there. People are on kik for just some fun and not to gain knowledge.
I'm not sure you can speak for "most users" on Kik then. I'm not just making a random guess. My post is based on years of hard evidence. When Kik Points was running in Kik from 2014-2016 it was seeing on average 3x as many transactions as Bitcoin was during the same period of time. I'm not sure you can really argue that as it's real data from Kik.

Kin is going to replace Kik Points within the Kik app and have even more usage and opportunities than Kik Points ever did. On top of that, unlike Kik Points, Kin isn't just tied to the Kik app. It's going to be integrated into 1000's of other apps. Some smaller, equal in size, or larger than Kik. However, with just Kik alone, based on hard data, it will become the most used crypto in the world (by transaction count) after it's fully integrated.
