I created a thread about this a year ago.
Post per day/ per month falling. and from it you can tell that the fall didn't start now or for a single reason.
As stated by Vod, there has been a fall in active members
There are other platforms where people can discuss about cryptocurrency and many left then because of the spam
This I believe has been combated to some extent.
Do you think people are turning to AI for readymade answers? and they only realize the importance of this forum after being scammed?
The above is why we have low active old members and for new members
Many don't even know about Bitcointalk. They are used to getting info from shit bloggers or social medias.
And how many care about how Bitcoin works again, all they care about is the price and how they are going ATH
You don't need Bitcointalk for that. People in X can tell them what they want to hear with poorly crafted excuse.
