By writing interesting, constructive, helpful posts, so other members can reward you for them. See the description here:
https://bitcointalk.org/index.php?topic=2818350.0. Getting merit is not easy but feasible if you have something useful to say. Read and learn, this forum has a wealth of information. Asking questions is OK, but short posts with little meaning or spamming will get you nowhere.
it seems that we should also have many friends here, because I look at other threads such as altcoin discussion or bitcoin discussion, I read postings from high-quality heroes and provide information, but in fact they are not given merit. this is not a justice, it is a conspiracy.
