Every genuine project you choose to promote as a bounty hunter should not be taken with levity.
First, before you set out to promote a project, study it and know what it is all about. Do not promote what you don't know.
Also, read through the instructions as prescribed by the bounty manager, so as not to destroy the project.
I have seen a situation where some hunters screwed up a project, because their thought is that every project is an ICO. Whereas, some projects are just for different purposes. Some just list directly on exchange without running an ICO.
Try to render a good service to the project that would pay you.
Avoid spamming threads in the name of trying to meet up with number of posts or deadline of submission. So that that the investors you are trying to disseminate the information to will not see you as a shit poster.
Showcase to the crypto world that you are able to provide a good service that would add value to the project and also to the cryptosphere in entirety.
