It's basically not about posting,you cant claim you deserve a merit simply by saying you make posts, anyone can come up with a post, even those who asks "when will bitcoin die","are you gonna hodl" kinda post.
It's all down to how well articulated your post is, and how it can effectively contribute to the forum,either you're contributing in real discussions(not spam megathreads, or paid bumping), or you're assisting someone at one point or the other.

But while doing that just simply take your mind off merits and have fun on the forum(through quality discussions),as thats what the forum was created for in the first place
