Thanks! yeah, all from bitcointalk since i haven't started a paid marketing yet, but it's on my to-do-list, i have registered for an account here back in 2017 but wasn't active at all. btw, since you are a staff here, could you give me some info about marketing on bitcointalk? i will be interested 
Since the forum no longer sells ads slots, you can do signature campaigns like some other services do: https://bitcointalk.org/index.php?board=52.0
But I'm not sure if you could achieve the same results as these services if you're going to only profit from placing ads?
