Because bounty hunters will be one of the major factor of the ICO's success that is why the bigger the budget the more bounty hunters will come.So that is why bounty allocation would be one major factor to decide these ICO's faith when it comes to advertisement to get more investors.
I thought 'bounty hunter' means a person who is doing some actions to promote the project in order to get some free coins, am I right? Like you join my TG channel and get some coins for that. In 2014 each bounty hunter got 1000 ETH for promoting Ethereum. I read this somewhere.
So, I don't see the connection between budget and bounty hunters. Bounty is a cheap (=free) way to promote your project.
Yes it is,bounty hunters are the ones who are promoting these ICOs in social media platforms like facebook twitter and youtube,and especially here in bitcointalk,the more bounty hunters that will join the ICO the higher chance of getting more investors to invest to that specific ICO.Bounty hunters doesnt want to participate a bounty which the allocation is too small that is why most of the bounty hunters are only joining those good paying ICOs.
