But aside from the sig campaign, you can find good payrates in YT campaigns.
That is, if you need to make a YT video for the project with good quality and if you have high number of subscribers.
Because not many can create a convincing video dedicated for the project as well as being influential in this platform.
In any case, joining these bounty programs will always not be fruitful as some of them are not really strong to gain the interest of investors.
So if you happen to join a substandard project, your effort will be worthless as you can't even get the tokens promised to the hunters.

To my own understanding, I believe higher stskes/tokens mostly go to the signature participants in bounty campaign, likewise YouTube, Article too. Very less goes to the social media(Twitter, Facebook, Telegram, Linkedin).

Pay a close attention to this and thank me later
