I think everyone has their own definite reasons for joining this forum. I'm sure they consider the benefits; it's just like when I joined for the first time. I wanted to increase my trading knowledge, so out of curiosity and engaging in discussions, being part of a forum became a habit. Collaborating and mutually sharing and seeking new knowledge creates a dependency on each other. It seems that for now, finding a forum purely for reasons without personal gain will be difficult. I think they have other specific reasons why they continue to be a part of the forum. IMO
If someone is looking for ways to make money online (crypto category), then one of the suggestions is to become a bounty hunter. In the past, many new users signed up because they wanted to become bounty hunters or airdrop hunters, but over time, the rewards were no longer profitable and user interest decreased. Older users turn to signature campaigns, but newer users won't know about this one if they don't have a mentor out there.
The main motive of new users is usually to make money while learning, but there are also those who do the opposite. The bitcointalk forum used to be considered a honeypot because of its bounty program that paid out thousands of dollars to participants, but then its bounty reputation was lost due to thousands of fake and undeveloped projects.
