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 amount of money that advertising projects use to allocate to bounty is not really important. No matter how much it is, it is only 1% - 3% of the total capitalization of the project and it will not change much. What I find most important is whether the project is good or not, if it is a good project, then allocating $ 10 million is also possible.
