We have two problems on this forum, more and more old members are leaving the forum and fewer and fewer new members are coming.
People get older, tired of their online habits, and life is taking its toll on them. Those are some of the reasons users are leaving, but there are of course others. I think we are getting some new members, however their reasons for joining and signing up is not to participate in discussions, learning, and spreading their own knowledge. That's the problem.
Most of the newbies that come to Bitcointalk can be divided in two:
1. Those who seek help with a problem they have.
2. Those who have read or have been told that they can earn on Bitcointalk.
The first group simply leaves after they have gotten the answers they are looking for.
Members who belong to the second group explore various earning opportunities (bounties, airdrops, the occasional signature campaign) and aren't really interested to participate in or try to create interesting threads and discussions.
In fact, I think there is a third group, but it is very difficult for me to say how big it is.
These are members who are really interested in crypto and want to learn something new, make new friends and hang out.
I say this from personal experience because I brought a few friends to this forum and I know well their motivation to join this forum.
Unfortunately, none of them are active on this forum anymore.
Some failed to even register due to the 'evil fee' rule and some gave up after some negative experiences and accusations from older forum members.
