It's just that many projects don't care much about bounty participants after they achieve their notoriety, thanks to bounty participants.
I doubt that will happen... This bounty is managed by HyperGrowth, which I believe is a third-party organization separate from Envion itself. So if the Envion team gets busy during the ICO, it won't affect the bounty admins. The admins from HyperGrowth are very active on Bitcointalk and Envion and I'm confident they will complete the entire bounty process.
