I think there are lots of bounty going on daily, but I do not know how many projects are good. If you know the project test before you do, I think you will succeed in the future.
As we know that bounty campaigns have become integral part of every ico project, if the project and product is good, it is quickly accepted by the community that is why we have seen good projects reaching their hardcap in few minutes as well. I like bounty campaign, I have participated it about three month ago. I got my first reward around 1 ETH just by doing 2 days of hardwork in this platform, That's pretty awesome right? Yeeh If you're lucky enough, you can find some bounty/contset with daily payment mate. Good luck.
