As a member of the forum and you're not growing in knowledge of the main purpose for which the forum was created for then it's a waste of time and energy for you. The forum is not just about earnings so if your growth in the forum is focused in ranks you are basically not growing.
You cannot earn in the forum without having some knowledge of why you are here. Why did I say that? Because 80% of discussions taking place on the forum are all about bitcoin, teaching people new things about bitcoin and any other new information about crypto So you can see that everyone who comes to this forum is there to learn about bitcoin and other cryptocurrencies. Even though they will engage in the signature campaign, they must have knowledge of why this forum was created and any other things they need to know. Because the signature campaign comes later when you spend some months on the forum, and I believe that for someone who is serious and ready to learn before ranking up, they will have something that they have learned. However, someone cannot rank up without the knowledge of which the forum was also created.
You are correct, but it is not always the case.
The forum has different sections, including local boards, and sometimes people get merit in their local boards, which is enough for them to rank up, and once you have ranked up, there is a chance for you to earn through the signature campaign because some of them allow posts in local boards and gambling sections, which have nothing to do with intensive Bitcoin knowledge.
However, I feel that any active user who has been a member of this community for more than four months should be able to learn a lot about Bitcoin and cryptocurrency because that is one of the key topics being discussed in various parts of this forum.
