So I think this merit mechanism is unfair, because it would allow those legendary or heroic users to profit from the merit mechanisms, and not to upgrade those who can not afford it.
I think selling your merit points to the other are wrong because it will giving you a red negative trust when you are getting caught by the moderator. Buying a merit points is cheating for those who.wants to rank up immediately. Merit points is like a commend in dota 2 you will gain it by posting a better answer in this bitcoin forum but when you post a low quality will will not have any merit points. And I think merit points system are good as of now.
