If anyone can provide a link to people giving merits after doing something good or productive please give link so I can earn merits not by asking people but because of my effort and for JR. Members to have a reference too.
You should demonstrate your ability to contribute to the forum by writing constructive, helpful, and high quality posts. In my opinion, it's not hard to rank up to Member rank (which is also your next rank). To be ranked up to this rank, you and me need only 10 merits. As you can see, I have got 1 merit after writing 10 posts, so in a word I can say that it is possible task. It's not easy but you can do it.
On the other hand, merits are not the main purpose we are here, right? I am not sure about your main objectives by joining the forum, but I have joined it because it can help me to learn valuable things about crypto-currency and blockchain technology from genuine users.
