I have seen a lot of cryptocurrency forums on the internet.
They tend to be different when they announce it, but what they did just copying almost all of bitcointalk useful threads.
I hope you are not trying to build that kind of forum.

If you want to get more users, you may consider to add paid to post feature with Dogecoin.
Promote it in doge community on telegram.
I saw dogecoin become newbie’s favorite on collecting free money.

Advanced or any cool features is not needed in your starts. It is already enough if users can generates free money from your site. Come on, am I wrong?
