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.
The problem lies in the fact that on the website of each project, the developers write that they are the best, the first, will bring huge profits to investors. And therefore it is very difficult among them to find exactly what will bring you profit from investing or participating in a bounty campaign.
