I don't mean bounty entries at all. Should I stop doing bounty for merit? Of course not. I just started earning merit. I've made 2 posts 300 words each and got nothing, I thought I posted usuful info. One of the post disapeared. I think it's not so easy to earn merit as you said. Anyway thanks for the answer.
Damn... 300 words? I wonder how you didn't get at least 30 merits 
Like it matters the number of words you use. But let me guess... You are talking about one of those posts in the Bitcoin Discussion board, right? Which are on page 80 of a Spam Mega Thread, will never be read by anyone (because they are buried with another 300 shitposts) and it's probably just repeating the same points that have been said in one of the previous 79 pages. No wonder you have 300+ posts and 0 merits...
