I believe that if the project is really good and that tokens are needed for utility then it's better to be paid in tokens rather than eth. Also, the dumping of tokens from bounty hunters usually happens so if they don't believe in the project then it's good to get rid of them at an early stage and let the believers have the tokens to support/use the product.
I agree with you, it is better to pay the bounty hunters a token instead of Ethereum. If you pay tokens to the bounty participants then it can help to promote their projects. Bounty hunters will trade their tokens immediately once they received it and listed on crypto exchange/s, it can cause dump but we can't blame them because they are the ones who worked for that money.
