I doubt that being a genuine person and interest to crypto alone would be enough in order to gain merit. Many people are interested to cryptos but not all of them are earning merit from other users in this forum. Quality of the posts being created to matter a lot. It should be informative enough or making sense for other people in order for them to give merit. But things differ sometimes. I won't say every post I made are worthy of a merit, but it is just some people are not participating that 'much' in merit sending. Some are saving their smerits for future purposes or in a sense that they are really that making an analysis before giving one. Some are saving in order to give to the people they know. But the bottomline is that, we should respect their reason whether they give or not because that is their smerit, simple as that.
