Few days back i found that you are not going to be promoted if you are unable to get more merit.
1 thing i know that you get a merit by making a good post which is helpful, but i want to know more ways to earn Merit?
how much merit 1 single account can give to other?
Sad to say but even if you have a good post or even a helpful one will not guarantee that you will get even a single merit. The only key to get a merit is if you have many friends here in bitcointalk that are willing to review and give you a merit. You are very lucky if you even get 1 merit every single day.
