Apart from the forum members who you think is popular and knowledgable? Is it all hero and legendary members or we got some side heroes too?
This forum does not stand by the ranks because there are even lower ranking accounts that has a deep knowledge about cryptocurrency so we cannot count them towards their ranks.
and also popularity comes from all perspective , there are popular account because of being scammer or negative tagged accounts yet they are popular , so I think this will be answerable depending to the views of each poster.
