As you are participating in bounty campaigns I conclude that you are scanning for new ICOs at least every week.
As I also like bounties here is what works fine for me:
I look for profitable bounties and once they paid me out I sell a few tokens for ETH or BTC.
When I come across a nice project in my search for bounties I join it, learn about it while doing the translation and getting to know how the team treats their customers etc.
If I feel confident in the team and project I invest some of my "free bounty money" into this project.
Once the token hits the exchanges I choose an exit point where I pull my initial investment and some profit out and continue to look for the next project.
Hope to have given you a new idea

This can be very profitable 30x and up. Make sure that you invest at the earliest stage possible if you plan on investing.
