So what if other forum compare bitcointalk.org ? Surely every forum wants to gain popularity like bitcointalk but obviously they cant reach at this level.
I understand that cryptotalk is a useless forum but if any other good forum tries to improve to become popular, there is no harm in it.

If crypto talk continues paying bitcoin to all thier member then they will have many spam post from users by having that paid per post forum. not a good idea if you want a honest discussion forum maybe they can find other alternative way to help users to earn but not that paid to post.
There are many forum tried that before andthat's not worth it for the money use by the owner and in long run they will just move to other forum if they think its not beneficial for them to be there anymore.
