this site is not as popular as it used to be.
It's still popular as it is. But with the growing number of places where people can gather information, they're going to the other ones that they have found instead of the forum.
Guess what? The information that is found on the social platforms just came to Bitcointalk, and they're scattered all over the place.
And influencers making their own communities outside the forum, they are going there and anyone can do that as long as they have the knowledge about Bitcoin and crypto in general.
