Rank in this forum means nothing.
There are legendaries which doesn't even know what is a private key. I was really impressed when I joined this forum and saw so many legendaries which were completely newbies in crypto.
The reason is that this forum had a bad time before the merit system was implemented. People created accounts here just for bounties and spammed everywhere. Now it is harder to rank up, so you will find newbie working hard to rank up.
You're absolutely right mate even me I'm member rank but I don't have much knowledge in cryptocurrency. Just like what you said, the last time that no need merit to rank up is easy to rank up even by just posting unuseful post, that's why forum rank is not a definition of how much knowledge you know in crypto.
