Yes if you happens to be lucky enough to choose the right bounty then yes it will be worth your time, take a look at Dia bounty, the value of Dia has rising so high that hunters will earn good reward from the bounty.
Good example. However, it is not correct. Yes, the project is showing very serious results. However, there were no payments to hunters yet, which means it is too early to talk about the success of bounty hunters.
Remember the DigitalBits project, they promised to pay out the awards for a whole year, while the project has grown very well in value. And in the end they deceived everyone and paid nothing to anyone.
If they decide not to pay, they are only playing on their reputation and it can ruin it. Their project will also be at stake. I just hope they and other projects in that position think of the aftermath before taking any action that will not be beneficial.
