By my calculation about 20 people in each position (except hero and legendary , which would be just 1) and 30 post max , you will have to spend around half a coin , which is around 200 $ , that is weekly. So there are websites in bitcoin community who probably spend around 1000$-1500$ on advertisement. Wow.
I get that signature campaign is the best but come on guys , lets say you have 100$ , what would you do , how would you advertise?
