No matter how funny it sounds, it is also true. In communism you are working for the good and wellbeing of the whole community in order to have a better life yourself. This is exactly what is happening on Hive.
If you want the price of Hive to go up and increase your portion of the pie, then you have to create valut through the posts or comments you make.
Creating good content and interaction adds to the overall value of the platform, and indirectly impacts you.
Disclaimer: It is free because you can choose to be a part of it or not and to what extent. It is also better implemented in many countries which got blamed for it.
