Don't get your hopes too high when promoting bounty projects especially bounties with very high allocations like in millions of $$$ ,they are never the same again unlike in the past ,all you have to do now is just depend on yourself and promote good projects and wait for end results.
You just hit it. Bounty is quite very disappointing these days. Even the ones you consider good project with integrity end up disappointing. The best bet is yo keep your mind open when promoting any project and be ready to accept whatever comes out of it, be it good or bad.
