Campaigns that pay in useless coins are not worth it. I could say bounty hunting is dead. There were good projects before that pays good but that was not the case anymore. You're also competing against bots so less reward for you. You aren't also guaranteed anything if a project fails. You'll most likely get useless tokens that will only flood your wallet. If you're not using both, maybe you'll get like 1 good project in like 6 months.

I can see bounty hunting becoming obsolete in the future unless something changes (Like changing the payment method to actual coins that has value).
