i feel interrest to parcitipate in this campaign but it's seem like not a bounty / airdrop more like giveaway. and just a few person will receive reward
It will be probably something like performing promotional tasks. Tweeting, posting, maybe referring...
Unfortunately, but keeping this campaign in a secret mood will not attract the attention of bounty hunters. The manager should start by explaining how the prizes will be distributed and who will be able to receive them.
