This may seem like a stupid question, but how will I ever rank up? I (almost) never post garbage but I can't seem to be able to get any merit. Paying for it on discord also doesn't feel moral.
You only have 5 more merits to go for regular member rank, so you can post about topics that are interesting to you and engage with thread in which you post, and try to provide substantive interaction with other members in the thread or bring up topics that are thread related that are interesting to you.
Personally, I think that it is helpful if you are interested in bitcoin, but there may be some alt coin threads that also allow for interactive and substantive discussions.
By the way, I don't understand some of your posts, but I did a google translate, and it appears that you have some decent posts. I merited your post here, just to give you the benefit of the doubt. Just keep trying to participate on broader levels in the forum and surely you will earn merits over time, and perhaps participate in some English threads, too which will introduce you to more forum members.
