If the advertisement is about crypto related services then advertising it in a famous crypto forum will target more audience that have full knowledge about how crypto works rather than thru random sites or with adsense campaigns.
$1000 expenses per week is nothing compare to the amount owners can supposedly gained if the advertisement works. Although obviously have some risk, it's way better to deal the advertisement here in the forum than anything else.
Any chance you know how much is the conversion rate on this signature campaign ?
It depends on the service you're advertising, you'll get more clients over time and as new members join even more.
I've learned something significant, most of the actions in the real world are inspired from the comments in forums and not just this forum.
You'll never know if Satoshi has been around since 2010 but with several alt accounts, you'll never know who is actually behind any account, but I know many important and influential people, powerful and rich people are in fact lurking around but mostly reading and staying in the shadows and some times comment on some game changing matters/ topics.
