I think for bountyhive it is highly recommended for beginners who first enter the world of bounty because bountyhive is very easy to run such as filling out our personal data, and just doing church services like social media sharing, content. And for Bounty0x I also recommend choosing again because not all the project bounty in bounty0x makes a payment.

For Newbie
BountyHive : 10/10 because it's easy to run and without making a report
Bounty0x : 8/10 it's easy to make a report, it's easy to understand, the project that is followed must really be reviewed
