Excuse me, I'd like to ask what the conditions are for getting more gems?

Personally, if I try to write long posts in various places or have extended conversations with someone, I get close to 10,000. When conversations are lively, it can reach that amount. Doing it every day might be tough, but if you chat with someone you click with, I think it's possible, right?

Unfortunately, I have no idea about the criteria... but I think if a short, content-less post gets a lot of replies and likes, it's highly rated, and even a useful post with little reaction is poorly rated. It's difficult to exchange useful information, so maybe it's better to post on a board that matches your interests?

I agree with Aruu's answer. I think they increase when you reply to comments on your own posts or comment on interesting posts, continuing the conversation. Doing things like glass bottles or the vanguard doesn't seem to increase them as much as commenting on community posts.

For now, it might be an option to post and comment here to see how it increases.
