I just rank up today at 70 activity but still I'm a Junior member because my merits are not enough, so I feel so sad..because honestly I'm having hard time earning it. I don't have much knowledge in bitcoin though I research but not all sink in my mind so its really hard for me to earn merit.. Is there any other way to earn merit except for quality posts? Please excuse my grammar.
You're not the only one. There are tons of user like you feeling that they will be stuck at their current rank because of the merit system but what they don't realize how the system will benefit them in the long run.
My advice for starters, avoid staying at "Bitcoin Discussion". I'm not saying all threads there are all useless but most of it is since it is mostly made out of newbies who have no initiative to do his/her own research first. Then put a lot of effort on researching about interesting topics that you can share or answer some topics in the threads that will be really helpful not only to the OP but for other members as well.
