To be honest, for both reasons, first you start with the emotion of the moment and knowing that you can "earn something out of nothing" or do what you already do on other social networks, then you get used to it and keep doing it without thinking about whether it's worth continuing to do so, really everything is based on money, power and influence you have, that's the truth.
To keep making money you have to have powerful friends who reward you with their vote, and if you do not get it, the effort is really worth nothing, I do not want to sound pessimistic, but on other networks you can get more honest comments.
So my main goal is, to do what I like (right now is photography) make a post about it and if I get profits that' s good, and if not, at least try to share with everyone what I have to show.
