I am new to this forum, but as far as I know it is not difficult to rank up. Because if you want to get merit, you have to use your own knowledge to help others or give good knowledge. So that they benefit a lot. Then you will definitely get merit. But if you post on altcoin board, you can never earn because it is spam side, to say here, everyone's post quality is same. So you have to post Bitcoin discussion, meta, economics, mining etc. If you post in these, you will definitely get credit.
