I don't actually see any tips and tricks in your post it's more like a "FACTS" about joining bounty campaigns. I will give you a example of tips that can help newbies:
• You should study the projects whitepaper/concept before participating to their program, so in the future you have an assurance that the reward you're going to received after the program has a value.
• Look for a project that the funds is escrowed because most likely some of the projects didn't pay afterwards.
• A reputable Bounty Manager is a advantage because they have more experience handling different projects as well as different participants.
• If you really want to maximize the profit you participate in all of their programs (ex. Signature campaign, social media campaign, translation campaign)
That's what tips and tricks all about (But the one I've made is more likely tips) and the list you've most are just a facts about bounty campaign.
The hard part is working on media campaigns and translation campaigns.
so better choose a campaign that we can do with the maximum! such as social media, telegram, medium (follow and claps). and others that are easy to do.
