Now since you shared telegrram group link,it reminded me that some groups have quizzes where they share tokens if you answer correctly to various questions.Would you consider something like that?
Those are interesting and fun, but sometimes it gets to chaotic, but worth a shot, it would make more people interested for sure.
If done properly its not chaotoc at all,and there areeven bots that can help you with that.Its a good way to spread info about project get people more involved.And it only cost you some tokens.
