You could as well read the rules here to get some directives as you seem like a total newbie.
Newbies Read before posting and you might as well find information there very useful.
It's just surprising that you at OP whom have been here for a long time just don't know the means by which, users are ranked. Even with you after attaining the 3rd rank (member) in the ranking profiling of the forum. You ought to know this for real.
If you would have bothered to click the links I've provided, you'd see that they contain the relevant information.
Merit system was introduced in January 2018, you posted very well at the time, but you do not know how to rank up. That is ridiculous.
Very good find!
The merit is harder to get. You'll need to post things people find really useful so they'll merit your posts.
The more he provides what bitcointalk reputed users like, the merit will not be hard to get. I noticed the process can be slow, but even the people that receive merit like how snail is crawling are enjoying this forum.
If the information is useful, it will be merited sooner or later. Is it something else you've meant and I'm missing?
I mean, yes, some areas tend to get merits easier than others. But I think that OP needs more than trying his luck here and there for 1-2 merits. Getting to 100 is quite a step.
