Many scam projects come out so I recommend joining bounty projects that are good at running a bounty. I am more in favor of joining bounty legit and trusted members because they have more experience in choosing legit bounty than newbies because the other bounty managers who are newbie mostly scam projects.
Joining a project bounty campaign that directly provides payments every week to campaign participants will provide more assurance than just analyzing based on unclear projects.
payment using coins that are already on the market and payments made every week I think is a good choice and maybe hopefully all projects can make payments like that.
