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 already got 5 merit points and this means that you have completed half the journey towards next rank (member). If you keep posting good quality posts, you will easily achieve the member rank in 1-2 months. You can utilize that time to sharpen your knowledge about bitcoins so that you make better investment decisions.
Regarding, other ways to get merit points, there are some ways but they are not ethical. Some members here are involved in buying / selling of merit points and they are getting recognized now and being punished by senior members.
