Wow they spend that much already? where did you get that data? BTW, looks like the post your shared was already deleted.
It didn't. The source is the post (from yahoo).
I'm going to post here even though you may delete my post due to my signature, but I happen to know the numbers and feel my post is relevant. The current campaign that I am watching over has paid out around 30btc since the end of September to participants.
IMO, yobit advertising in the forum is not wasting of money because they have been advertising even in the early stage, I am not sure why they stop but I believe they will come back again any time soon.
I'm not sure how "advertising even in the early stage" is related to success, but that was clearly a joke.
