Personally, I'm involved in bounty projects, I think it's the most popular and highly paid job in cryptocurrency where you don't have to invest any money
but I think the job of participating in a bounty campaign will be more difficult because you have to have prior experience to do research on a project. if your research fails then you will find a project that does not pay the maximum so you should be wiser in finding a bounty campaign
Not only is the bounty campaign harder, it is even paying less than ever, especially when we participate in social campaigns, sometimes it takes several months to complete but the income is less than $100, the saddest perhaps is that we can receive promises about the date listed and then the project team evaporates from our lives. Right now, if not invest or mining and want to make crypto money, it has so many problems, instead of getting tired and trying to solve these problems, a little initial investment will make things easier for us.
