Social networks version 2.0 such as Facebook or Twitter, etc. are currently dominating the market by providing free services to users, then they collect the user's information and make a profit on it, for example, by serving ads. The appearance of SocialFi will upgrade those traditional social networks to the Web 3.0 platform. At this time, power instead of concentrating on an intermediary company will be placed in the hands of users. They have the power to decide the survival of that model, whether it is possible to monetize their data.
