It seems to me that you have already received answers to your questions

We are all different and have different experiences, knowledge and reasons to participate in this forum.
Some are beginners and come here to learn something about crypto.
Some just want to connect with other people from their local community.
Some are interested in various paid projects in the market section of the forum.
We also have owners of crypto firms who come to this forum to present the services and products of their companies.
Since we don't know you, neither I nor the other members of this forum, we really can't answer your question about what you gain by participating in this forum.
Only you can answer that question.
