It would be great if project decided to pay for Bounty campaign is stablecoins.
Not all of them can afford that, most of the projects relies only from the investment of the people, they maybe have a capital but that's for sure a little amount only, that's why they fail because at this point, people are not into investing.
We need to witness a bullish market again so people will be attracted to invest again and I believe it will come if not this year then the following years.
Unfortunately, they prefer paying in their own tokens which usually cost nothing after distribution.
If they fail, then just don't expect you'll get nothing.
Sometimes bounty hunting may look like investing as well, sometimes we lose and sometimes we win, bounty hunting is just not risky compared to investing with real money which investors are doing.
