It's normal to feel that, especially as a newbie. Cause I also felt the same way back then, and sometimes I still feel it up to this day. But it depends on the topic or the thread cause there are topics that I am not really that knowledgeable so I kinda doubt myself with what I'm about to share, if it makes sense or what I am saying is correct.

Seeing the ranks surely affects some of the lower ranks. Sometimes it's kinda intimidating to interact with higher ranks cause obviously, they've been here in the forum for a long time and already have a lot of knowledge. But the positive side of interacting with their threads or topic, you'll gain knowledge based on their experiences here. It's like, being surrounded by users with enough knowledge will make you learn things you don't know in the crypto space. Also, if you really want to share what's on your mind, feel free to share it since that's what the forum is for. You can be corrected, you can ask and learn new stuff, and you can share your ideas to others as well.
