Detailed description of the idea (1 idea - 1 post)
Black Market. Every day, a Black Market offer pops up, for example: Spawner, credits, service. Players bid all day to get it. Bidding ends at the start of the next day. The person who bids the amount no longer gets the money back if they are not the winner. This way, I see that a lot of the server's balance would definitely be destroyed.
