It's not difficult, no, but I don't know whether you already saw some of the bounty hunters that participate in as many bounties as possible. It's really nuts because the amount of work it takes to make all those entries, follow the projects and do the right steps in the right order and to keep track of everything equals several hours a day. So basically they could work a real job
