Of course it will, because a new project need attention for the new investors and one of the best way to promote it is doing the airdrop or bounty campaign. Giving the token/coin allocation for bounty and airdrops is a must for new projects (except a project that is under big name company, maybe they won't need it anymore).
Airdrops and bounty campaigns are one of the quick and precise ways to promote new projects by investors, and this is a must for investors, the results to be achieved are also comparable to what they promote.
