As long as new projects and coins enter the cryptocurrency world, as well as this forum exists, Bounty programs will run. These new projects and old projects which wish to refine their strategies need the help of bounty hunters to spread the awareness across all over the globe.
Nowadays, majority of the ico bounty campaign they run long period of time, unlike 2017 most of it run only for 1 month up to 3 months only, comparing into our presence now were most of the ico run for 3 months up to 6 months or more. Which is became a burden instead of opportunity for the bounty hunters. Then, usually after the ico the distribution it takes 1 months or 3 months and sometimes it exceed more.
