Already in the middle of the year 2018 and there is no popularity of KIN in the crypto community, how then will it become the most used by the end of the year. Well, I like the fact that you aim high but doubt if it will because there are more better and more stable social network than it.
Kin is set to launch within the Kik app as soon as the end of June (this month). It will also be releasing it's standalone app, Kinit, to the public in July.
With just the Kik integration alone, it's possible it will have more transactions a day than any other coin in the crypto space soon after integration. However, this is even more likely to happen before the end of the year as it's further integrated and especially once Kinit is generating transactions as well.
The "crypto community" is extremely small when compared to the mass consumers of digital apps in the world. KIN isn't trying to convince current crypto users to get on board, nor does it need to. KIN is focusing on the billions of consumers that use apps daily that will be using crypto for the first time. Kik alone has 300,000,000 users with about 15,000,000 active monthly. All it needs to do is get it's current user base earning and spending in KIN and it will become the most used crypto in the world.
