https://start.edgeless.io/bitcointalk-bounty-campaign/ Join our new BitcoinTalk campaign for a chance to get 1000 EDG As a bonus, all participants get a 20% share of affiliate revenue commissions. A personal affiliate link is added to the BitcoinTalk signature and avatar.
i get an email about the signature campaign.i think it is nice.This team started marketing on this project.I hope more and more people join the edg.
but there is a description to all participants get a 20% share of affiliate revenue commissions. A personal affiliate link is added to the BitcoinTalk signature and avatar.

and whether only 1 person will be the winner of 1000 EDG and how about the other participants

Only 1 person to get 1000 EDG seems very cheap and not worth the effort. The initial campaign was much more rewarding for every user involved. I don't think this will attract much people to want to join.
