Make substantive posts. Try to aim for a goal of 4-5 posts a day, and that's posts that either ask a question or answer someone else. Try to share your own personal experience with crypto, or whatever the topic is at hand. Share any advice you have to newcomers. There's thousands of things you could say to submit a post and be helpful to the forums. Generally, just try to make the forums into a place you want to actually visit and spend time on and the posts will come naturally.
