Here's an example:
Sapien.
Every post, like, share you earn their native token, SPN.
It was launched I think around Q1 of 2019 but even with all the hype they still struggle to have a decent amount of users within their platform.
Another one is Empowr. Almost entirely the same as Facebook but with tokens as a reward for each action you do within their platform.
Also struggling to have enough users to make it into the mainstream.
If you're planning on launching one; It should be unique, rewards its users, cannot be exploited for its rewards and has good tech support.
Me neither see a successful social network crypto, I add your example: ONZ.
I think this ONZ is similar with SPN in general. They launched in Q1 2018, listed in some exchanges but very low buyers and very low price which is almost not worthy.
Another struggling social crypto: UHIVE
Quote: "It has been in the making for 3 years now, it is mobile based, designed from the start to support virtual reality and powered by A.I., The concept was derived from human needs and psychology, and it has new, unique and innovative concepts.".
Seems this UHIVE is still struggling until now even their App has been launched as built several years ago, there is also an unpleasant story that the extended bounty participants worked from 3 months since beginning of April 2018 to around 6 months (end of Sep 2018) and not paid until now.....
Reportedly it has been asked many times but the answer is always the same ... Token will be given as payment after installing the application and doing a number of certain new jobs ... not payment because it has worked in the past year.
So I hope the project developer will be able to formulate the concept and find much better solution than those examples unsuccessful social network crypto as this is the right timing for social network to be connected with crypto by bull run moment and established social network.
You're right! This social network is created to unite people engaged in cryptocurrencies and blockchain. There will be no rewards for content or actions.
