I began to think this would be a waste of time with everything I learned because almost all the projects I had followed ended in scammers. Is this a waste of time for me? 
Nowadays mate its hard to find a legit bounty projects that's good to participate and make for it, especially these days which is still considered in a declined market. In my part I keep try doing signature bounties hoping that will get success soon and could make earn money. I'll just put all trust into my bounty manager and the project that I supported.
