There is absolutely no dividend stipulated amongst users who brings in new members in this forum as much as there is no reward given to any existing Bitcoin holders who in any way brings or introduces anyone into the Bitcoin industry nor this Bitcointalk platform,
Why does everything need to be incentivized? This is a discussion forum, where the incentives should simply be the fact that there will be more people to converse with.
As for incentivizing Bitcoin sort of "evangelists", you can incentivize through your own ways. Like how Andreas Antonopoulos grew a decently-sized YouTube channel, and sold a good number of books. If you're thinking of direct Bitcoin incentives, then lol that's one way of making it look like a total marketing scheme.
This might just sound uninteresting but it is pointing at those who are in competitive manners of brining in persons into the forum without being properly oriented. Most of the persons brought into this forum never had the passion being here in the first place but some of us ignores how substantial their contributions and what their unwilling potentials to the forum would result to. To an extend, these unworthy persons being convinced in the forum leaves their forum accounts vacant flooding the forums with domant users accounts.
It's pretty similar to any other niche. While having lots of dormant accounts isn't good, it's not as much of a huge problem as you think.
Contrarily this is also how some of our bitcoineers convinces unwilling individuals to get into the Bitcoin industry and Invest their funds with an explanatory manner of just focusing at making incomes while they ignores to explain about the risks involved to them and at the end of it they are held responsible for misleading them to the lost of their funds while the Bitcoin industry becomes a fraudulent technology to them due their lack of being oriented about the basics potentials of the Bitcoin technology.
Unfortunately, that's how manias work. We had a similar flooding of people in the pandemic where people flocked into stock markets because of boredom and due to the pursuit for income. The only difference is that hacks are a lot less damaging when talking about traditional markets.
I don't know if these fellows who are desperate of brining people in to the platforms and in the Bitcoin industry are after of self recognition or whatever.
Maybe, or maybe sometimes people are just too excited when they're making money that they want to talk about it. It's pretty different from person to person.
