One user in a conversation told me that one of the admins has a lot of bitcoins that belong to the forum or to him (I still don't understand).
If these are the forum's Bitcoins? At the current rate, this is 120 million dollars. Why then doesn't he spend several million dollars on promoting the forum? To increase activity and all that. Or create some kind of system that would reward quality posts financially, or ultimately give users cash prizes.
And where are these bitcoins spent at all?
Does he really need to do that? Bitcointalk is already a well known site and everything here is sustainable. So I guess there's no need to spend for promoting the forum since people already sharing the information that this forum exist and I think that's enough already.
Also we can see that Bitcointalk still the famous bitcoin and crypto platform so there's no point of doing such thing you mentioned since it doesn't competing to any platform.
Also people here don't ask any financials or prizes from administrator so maybe you or other people should stop those thoughts that if they have lots of money they should give something back to their community.
