I see you joined in Leasehold signature campaign and that campaign was held this year, a couple of months ago! So, I believe you know things; you have to pick the best bounty project that has a working product or unique technology, well-written whitepaper, good partnerships, strong media supports. Right now, the number of scam bounties is very less; most of the campaigns are paying to their hunters! Bounty Detective's bounties, Bubbalex, Murat's campaigns are doing well. You may have a look there! Good luck
